analyse de e+ e- --> tau+ tau-
version - 6 mai 2002
plot.2.ius
Dans ce texte nous n'envisagerons que le cas (outre 2 neutrini) où
l'un des taus se désintègre en 3 corps chargés (tau_A) et l'autre
(tau_B) en une particule chargée unique.
Ici on utilise le fichier "p31n" (simulation-babar - octobre 2001),
pour représenter quelques histogrammes.

L'histo 14 caractérise l'offset dans la reconstruction des événements
(coordonnées en microns). Quoiqu'il y paraisse, la forme de cet histo 14
est similaire à celle de la simulation-Jussieu (item précédent) au
premier bin près, why ?

L'histo 413 laisse apparaitre une moyenne de 3.1, pour 3.0 théorique.
L'histo 414 n'est pas un créneau constant entre 0. et 1..
A noter le grand pic pour les probabilités nulles,
et une montée linéaire vers des probabilités de 0. à 1.,
