A narrow scalar resonance at 325 GeV?

We propose to identify the excess of events with four charged leptons at E\sim 325\GeV seen by the CDF and CMS Collaborations with a new `sterile' scalar particle characterized by a very narrow resonance of the same height and branching ratios as the Standard Model Higgs boson, as predicted in the framework of the so-called Conformal Standard ModelComment: 4 pages, 2 figures, text and references correcte

Superconducting ''transistor'' acts as high-speed switch

Cryogenic, three-terminal device yields current-voltage characteristics of ordinary transistor. Device consists of two superconducting tin rods in a crossed-wire geometry, separated by a thin gold film. New construction technique is described and possible applications are discussed

Results of Soft-Diffraction at LHCb

The LHCb detector with its unique pseudorapidity coverage allows to perform soft-QCD measurements in the kinematic forward region where QCD models have large uncertainties. Selected analyses related to soft-Diffraction will be summarised in these proceedings. Energy flow and charged particle multiplicity have been measured separately in different event classes. They give input for modelling the underlying event in pp collisions. Prompt hadron ratios are important for hadronisation models, while the $\bar p/p$ ratio is a good observable to test models of baryon number transport.Comment: Presented at EDS Blois 2013 (arXiv:1309.5705

Symmetries of higher-order string gravity actions

Chitra Banerjee Divakaruni: A Bibliographic Review of Resources for Teachers

As a poet, short story writer, novelist and essayist, Divakaruni has gained a wide national and international audience. Her writing in multiple genres addresses cross-cultural complexities of self-identity, family relationships and community values. Most notable has been her continuing concern with these issues in connection with the experiences of Indian and Indian American women. Reviews of her work emphasize her boldly imaginative style of story-telling, poetic sensibility, creativity in genre crossing, and commitment to breaking down boundaries between serious and popular literature

T-Duality and Two-Loop Renormalization Flows

Manifest T-duality covariance of the one-loop renormalization group flows is shown for a generic bosonic sigma model with an abelian isometry, by referring a set of previously derived consistency conditions to the tangent space of the target. For a restricted background, T-duality transformations are then studied at the next order, and the ensuing consistency conditions are found to be satisfied by the two-loop Weyl anomaly coefficients of the model. This represents an extremely non-trivial test of the covariance of renormalization group flows under T-duality, and a stronger condition than T-duality invariance of the string background effective action.Comment: 18 pp., plain TeX + harvmac.

Conformal Standard Model and Inflation

This article presents a possible inflation scenario as a consequence of non-minimal gravitational couplings in the Conformal Standard Model. The model consists, in comparison to the SM, of additional right-chiral neutrinos and complex scalars coupled to the right-chiral neutrinos but not to the SM particles. The inflation is driven by two non-minimally coupled fields one being the usual Higgs and the other one of the sterile scalars. It turns out that in this model the tensor to scalar ratio and spectral index can match the current data for a wide range of parameters
