Method of Monte Carlo grid for data analysis

This paper presents an analysis procedure for experimental data using theoretical functions generated by Monte Carlo. Applying the classical chi-square fitting procedure for some multiparameter systems is extremely difficult due to a lack of an analytical expression for the theoretical functions describing the system. The proposed algorithm is based on the least square method using a grid of Monte Carlo generated functions each corresponding to definite values of the minimization parameters. It is used for the E742 experiment (TRIUMF, Vancouver, Canada) data analysis with the aim to extract muonic atom scattering parameters on solid hydrogen.Comment: 16 pages, 10 figures, submitted to NI

How to optimize the sport-study in Geneva for team sports, taking as a benchmark the educational system of different football academies in Europe ?

Today, in Geneva (and in Switzerland), practicing a sport at a professional level, and continuing the studies, is something difficult to combine. Not all the young athletes, playing in an Elite Team, have the possibility to follow an adaptable sport-study program. The main problem that the sport-study is currently encountering is a question of budget. That’s why only the young athletes with a “Swiss Olympic Talent Card” can accede to the post-mandatory school in the sport study program. However it is interesting to see that in Geneva (during the year 2012-2013), 732 young athletes had a Swiss Olympic Talent Card. Out of these 732 young people, 79 are enrolled in a secondary school in the sport study program, and 77 in the post-mandatory, which represent 21% of all the holders of the Swiss Olympic Talent Card. What are the other 79% doing? In order to compare the different educational system within sport organization it is easier to take into account only one specific sport. In this thesis, football will be the benchmark. Football is the most popular and accessible sport. Even if Switzerland does not have the most followed Championship, the country is one of the best in terms of promoting new generations of players and has a high potential of young talents. Between 28% and 36% of the players in the Swiss Championships (Super League and Challenge League) are under 21 years old. These numbers demonstrate the quality of the football development in Switzerland. However too many young players are quitting school because of a lack of measures that would enable them to combine their sport with their studies. The question this thesis will try to answer is how to optimize the sport-study in Geneva for team sports in order to enable the young athletes to combine their passion, and their future reconversion. This thesis will concentrate on three football academies in Europe: Crystal Palace FC in England, The Olympique Lyonnais in France, and Servette FC in Switzerland. The goal is to analyse what and how things are done abroad, and to give recommendations to improve the current measures in Geneva

Muon Catalyzed Fusion in 3 K Solid Deuterium

Muon catalyzed fusion in deuterium has traditionally been studied in gaseous and liquid targets. The TRIUMF solid-hydrogen-layer target system has been used to study the fusion reaction rates in the solid phase of D_2 at a target temperature of 3 K. Products of two distinct branches of the reaction were observed; neutrons by a liquid organic scintillator, and protons by a silicon detector located inside the target system. The effective molecular formation rate from the upper hyperfine state of $\mu d$ and the hyperfine transition rate have been measured: $\tilde{\lambda}_(3/2)=2.71(7)_{stat.}(32)_{syst.} \mu/s$, and $\tilde{\lambda}_{(3/2)(1/2)} =34.2(8)_{stat.}(1)_{syst.} \mu /s$. The molecular formation rate is consistent with other recent measurements, but not with the theory for isolated molecules. The discrepancy may be due to incomplete thermalization, an effect which was investigated by Monte Carlo calculations. Information on branching ratio parameters for the s and p wave d+d nuclear interaction has been extracted.Comment: 19 pages, 11 figures, submitted to PRA Feb 20, 199
