Mixing and $CP$ violation in charm at LHCb
Violation of the charge-parity (CP ) symmetry has been observed in several systems (kaons, Bd,s mesons), all of which are related to the down-quark sector. It remains to be observed in the up-quark sector, where only the c quark manifests flavour oscillations. The LHCb experiment is now playing a ma...

Sumario: | Violation of the charge-parity (CP ) symmetry has been observed
in several systems (kaons, Bd,s mesons), all of which are related to the down-quark
sector. It remains to be observed in the up-quark sector, where only the c quark
manifests flavour oscillations. The LHCb experiment is now playing a major role in
charm physics. This document reviews some of the latest results on charm physics
from LHCb, specifically on the measurement of CP asymmetries in the D±
(s) → η′π±
and Λ+
c → ph+h− channels, as well as the most precise measurement of mixing and
CP -violation (CPV ) parameters with D0 → Kπ decays. |
