description | In 2019 LHCb will have one of the biggest upgrades of all LHC experiments. The project aims to study event shape variables for the LHCb trigger. Event shape variables are used to help identify events as having a higher likelihood of containing a beauty hadron within the LHCb acceptance from Minimum bias. Samples of each process are generated using the Pythia program. Fox Wolfram Moments, sphericity and thrust are applied to the data by selecting events with pseudorapidity $2.2 < \eta < 4.5$. The sphericity variable can reject 50% of minimum bias events, while selecting 90% of events containing a beauty hadron within the LHCb acceptance and with $p_{T} >$ 2 GeV. |
