Since the spring of 2024, a system has been in operation at CMS to acquire data at 40 MHz (i.e., without a trigger filter) related to candidate physics objects reconstructed by the Level-1 trigger system. This system is referred to as L1 Trigger Data Scouting (L1DS). The study proposed in this thesis focuses on the analysis of a subset of data collected using L1DS, with the aim of searching for signals distributed across multiple bunch crossings and exhibiting long temporal development, which may indicate the presence of exotic particles.
Dalla primavera del 2024 a CMS è in produzione un sistema per acquisire a 40 MHz (ovvero senza filtro di trigger) i dati relativi ai candidati oggetti fisici ricostruiti dal sistema di trigger di primo livello; tale sistema è indicato come L1 Trigger Data Scouting, L1DS. Lo studio che si propone in questa tesi verte sull’analisi di alcuni dati ottenuti con il L1DS, al fine di cercare tracce distribuite su più bunch crossing, con sviluppo temporale lungo che possa evidenziare la presenza di particelle esotiche.

Abstract
Since the spring of 2024, a system has been in operation at CMS to acquire data at 40 MHz (i.e., without a trigger filter) related to candidate physics objects reconstructed by the Level-1 trigger system. This system is referred to as L1 Trigger Data Scouting (L1DS). The study proposed in this thesis focuses on the analysis of a subset of data collected using L1DS, with the aim of searching for signals distributed across multiple bunch crossings and exhibiting long temporal development, which may indicate the presence of exotic particles.| File | Dimensione | Formato | |
