New Application of Functional Integrals to Classical Mechanics

In this paper a new functional integral representation for classical dynamics is introduced. It is achieved by rewriting the Liouville picture in terms of bosonic creation-annihilation operators and utilizing the standard derivation of functional integrals for dynamical quantities in the coherent states representation. This results in a new class of functional integrals which are exactly solvable and can be found explicitly when the underlying classical systems are integrable.Comment: 13 page

Renormalization Ambiguities in Chern-Simons Theory

We introduce a new family of gauge invariant regularizations of Chern-Simons theories which generate one-loop renormalizations of the coupling constant of the form $k\to k+2 s c_v$ where $s$ can take any arbitrary integer value. In the particular case $s=0$ we get an explicit example of a gauge invariant regularization which does not generate radiative corrections to the bare coupling constant. This ambiguity in the radiative corrections to $k$ is reminiscent of the Coste-L\"uscher results for the parity anomaly in (2+1) fermionic effective actions.Comment: 10 pages, harvmac, no changes, 1 Postscript figure (now included

Non-Universality Effects and Dark Matter in Gravity Mediated SUSY Breaking

Dark matter detection rates for supergravity models with R parity where supersymmetry is broken at a scale >~M_G are discussed. Non-universal soft breaking masses in both the Higgs and squark sectors are considered, and it is seen that these can effect rates by a factor of 10-100 when m_X <~ 65 GeV (X=lightest neutralino) but otherwise make relatively small corrections. The b->s+\gamma branching ratio is seen to correlate with detector event rates, large (small) branching ratios corresponding to small (large) event rates. Effects of precision determinations of cosmological parameters or event rate predictions by future satellite experiments are discussed for the LCDM and the vCDM models.Comment: LaTeX 7 pages,4 figures, requires espcrc2.sty available from http://dept.physics.upenn.ed

Amor materno: esencia corpórea en tiempo de covid-19

Social expectations seek a new meaning to the performance of being a mother in time of COVID-19. The maternal essence becomes the corporeal transcendence to understand and understand the cultural demands, in the coexistence of the corporeality of being a doctor in times of uncertainty. This is a key category to start this essay, which has as its purpose a deep reflection from my maternal feelings and the documentary review. Where I seek to share experiences and concerns in this complex and intertwined perspectives in a process of reflection from the complexity of living together as a conglomeration of subjective interrelationships of being the mother of a doctor and a doctor who needs love in times of COVID-19Las expectativas sociales buscan un nuevo sentido a la actuación de ser madre en tiempo de COVID-19. La esencia materna se convierte en la transcendencia corpórea para entender y comprender las exigencias culturales, en el convivir relacionar de la corporeidad de ser médico en tiempos de incertidumbre. Esta es una categoría clave para iniciar este ensayo, el cual tiene como propósito una reflexión profunda desde mi sentir materno y la revisión documental. Donde busco compartir vivencias e inquietudes en estas ópticas complejas y entrelazadas en un proceso de reflexión desde la complejidad del convivir como un conglomerado de interrelaciones subjetivas de ser madre de un médico y un médico que necesita amor en tiempos de COVID-19

Non-Universal Soft SUSY Breaking and Dark Matter

An analysis is given of the effects of non-universal soft SUSY breaking masses in the Higgs sector and in the third generation squark sector, and it is shown that they are highly coupled. Analytic expressions are obtained for their effects on the parameters $\mu,m_A$ and on the third generation squark masses. Non-universality effects on dark matter event rates in neutralino-nucleus scattering are analysed. It is found that the effects are maximal in the range $m_{\tilde\chi_1}\leq 65$~GeV where the relic density is governed by the Z and Higgs poles. In this range the minimum event rates can be increased or decreased by factors of O(10) depending on the sign of non-universality. Above this range Landau pole effects arising from the heavy top mass tend to suppress the non-universality effects. The effect of more precise measurements of cosmological parameters on event rates, which is expected to occur in the next round of COBE like sattelite experiments, is also investigated. Implications for the analysis for dark matter searches are discussed.Comment: 28 pages, latex, and 7 fig

ACINO: Second year report on dissemination and communication activities

This ACINO deliverable presents the communication and dissemination activities performed by the consortium during the first two years of the project. We have communicated using our website, Twitter account and by various communication actions: The website saw over 3000 unique visitors during the first year and over 4000 during the second year; The consortium Twitter account had 49 followers at the end of the first year and 80 at the end of the second year. We posted 50 tweets during the first year and 40 more during the second year; We also held a press release and an interview in a magazine during the first year, and had three more similar communication actions during the second year. The dissemination activities have been composed of participation in public events where the goals and concepts of ACINO were presented via publications, presentation, workshops, courses and demonstrations. Overall, over forty different dissemination activities have been performed: An article has been published in peer-reviewed, open access Journal of Green Engineering; Eighteen articles have been published in conferences: four during the first year and fourteen during the second. One of them was a post-deadline and six were invited papers; We have co-organised three workshops: the Workshop on Network Function Virtualization and Programmable Networks at EUCNC 2015, the first Workshop on Multi-Layer Network Orchestration (NetOrch) at ICTON 2016 and the stand-alone ONOS/CORD workshop; We have held 16 talks, tutorial, courses and demonstrations; Consortium members have won two prizes for work related to ACINO: a team of developers won the 3rd prize of the ONOS Build Hackathon, and Telefónica won the Best SDN-NFV solution award at the LTE and 5G World conference by presenting a solution in which Sedona Systems was involved; We have contributed to six IETF standardisation documents and done some implementation and test of these standards. We have contributed to two open source projects: the NetPhony and ONOS controllers, with the implementation of main features being accepted and merged to the core code of these open source projects. Finally, the project has devised detailed plans for its dissemination activities for the last year of the project. We have: Confirmed plans for the organisation of a workshop, the second edition of the NetOrch workshop, co-located with the ICTON conference; A solid plan for continued dissemination in conferences (already five accepted conference papers, five talk invitations and a list of conferences of interest) and in peer-reviewed journals, with one article accepted for publication in the Journal of Lightwave Technology, two articles under review and plans for four more; Some more planned contribution to open source projects

Caracterización teórica fundamentada por las metodologias analítica y cognitiva para la toma de decisiones, en el fútbol formativo en niños de 10 a 12 años

Hoy en día son necesarios en los procesos formativos (Fútbol base), profesionales dispuestos a implementar metodologías que aporten y fortalezcan a el crecimiento global del deportista. (Niños dispuestos a formarse) y no a la sed de gloria inmediata, con un presente vacío en la etapa de desarrollo transitoria, haciendo hincapié en la creatividad y la alegría que produce el juego. La implementación de una metodología en el fútbol formativo dependerá: del deseo por los resultados inmediatos por parte del entrenador, donde mecaniza situaciones aisladas de juego que fortalezcan gestos técnicos específicos en los deportistas futuros o la intención por una formación óptima con vistas al futuro donde respete y priorice la globalidad del ser (Principios físicos, técnicos, tácticos, cognitivos, psicológicos, emocionales y sociales), en donde la clave sea interpretar los numerosos acontecimientos que ocurren durante el juego, para lo que deberá utilizar todas aquellas estrategias que permiten visualizar, procesar y ejecutar, en el menor tiempo posible la acción del juego más indicada para la situación

Minimal See-Saw Model for Atmospheric and Solar Neutrino Oscillations

We present a minimal see-saw model based on an extension of the standard model (SM) which includes an additional U(1), with gauge charge $B - \frac{3}{2} (L_\mu + L_\tau)$. Requirement of anomaly cancellation implies the existence of two right-handed singlet neutrinos, carrying this gauge charge, which have normal Dirac couplings to $\nu_\mu$ and $\nu_\tau$ but suppressed ones to $\nu_e$. Assuming the U(1) symmetry breaking scale to be 10$^{12-16}$~GeV, this model can naturally account for the large (small) mixing solutions to the atmospheric (solar) neutrino oscillations.Comment: 14 pages, latex, no figure
