Lifetime Measurement Of The Xi_C^+ Using Belle Ii Monte Carlo, Paul Gebeline
Lifetime Measurement Of The Xi_C^+ Using Belle Ii Monte Carlo, Paul Gebeline
Honors Theses
This analysis uses simulated data from the Belle II experiment to measure the lifetime of the Xi_c^+ baryon. Three different decay modes are investigated to explore the feasibility and accuracy of such measurements at Belle II. The Xi_c^+ lifetime is measured using one of these modes after reducing backgrounds from sources other than the decay of interest. The final result is 464 +/- 15 fs, which is consistent with the expected result of 442 fs within uncertainty. This result shows that Belle II can make competitive measurements of particle properties and decays.
