Abstract
The LHCb experiment has collected the world’s largest sample of charmed hadrons. This sample is used to measure mixing and to search for direct and indirect CP violation, and its sensitivity is now approaching the Standard Model expectations. In this document, the most recent LHCb results on CP violation in charm sector and on charm mixing are reported.
Highlights
CP violation (CP V ) plays an important role in the understanding of particle physics and of the entire Universe
As the D0 system is the only up-type quark system in which flavour oscillation and CP V can be observed, it offers a privileged window to look for New Physics beyond the Standard Model
A prediction based on the Standard Model gives an upper limit for the CP asymmetry of about 1% [7]; further enhancements could result from contributions from physics beyond the Standard Model
Summary
CP violation (CP V ) plays an important role in the understanding of particle physics and of the entire Universe. A prediction based on the Standard Model gives an upper limit for the CP asymmetry of about 1% [7]; further enhancements could result from contributions from physics beyond the Standard Model This quantity has already been measured by the CLEO collaboration [8], by the Belle collaboration [9], and by the LHCb collaboration [10] using Run 1 data. The branching ratio is in agreement with the Standard Model expectations and the measurement of angular and CP asymmetries has been performed, using data collected from 2011 to 2016 (∼ 5 fb−1 of integrated luminosity). Where the first uncertainty is statistical and the second is systematic
