Study of the jet-jet invariant mass resolution for events with 2 jets and 1 photon in the final state in e+e− interactions

Summary

A Monte Carlo study is made for events with 2 jets and 1 photon in the final state. The selected events are kinematically reconstructed from the measured directions taking into account the experimental resolution. In this way we get a jet-jet invariant mass with an uncertainty\(\sigma _{m_{jj} } \leqslant \) GeV. Moreover a complete study based on this method is made for the experimental detection of a neutral, Higgs boson (H0) produced via the toponium resonance.

Riassunto

Si effettua, uno studio di Monte Carlo per eventi con 2 jet e 1 fotone nello stato finale. Si ricostruiscono cinematicamente gli eventi scelti dalle direzioni misurate prendendo in considerazione la risoluzione sperimentale. In questo modo si ottiene una massa invariante di jet-jet con un’incertezza\(\sigma _{m_{jj} } \leqslant \) GeV. Inoltre si effettua uno studio completo basato su questo metodo per la rilevazione sperimentale di un bosone di Higgs neutro (H0) prodotto attraverso la risonanza del toponio.

Резюме

С помощью метода Монте Карло исследуются события с двумя струями и одним фотоном в конечном состоянии. Учитывая эксперименталяное разрешение, из измеренных направлений кинематически реконструируются выбранные события. Таким образом, мы получаем инвариантную массу “струя-струя” с неопределенностью\(\sigma _{m_{jj} } \leqslant \) ГэВ. Проводится полное исследование, основанное на этом методе для экспериментального детектирования бозона Хиггса (H 0), образованного через резонанс топония.
