Measurement of the CKM angle γ using the B± → D∗h± channels
Aaij, Roel; Chobanova, Veronika; Hao, Lei (Springer, 2023-12-01)[Abstract] A measurement of the CP-violating observables from B± → D∗K± and B± →D∗π± decays is presented, where D∗(D) is an admixture of D∗0 and ¯D∗0 (D0 and ¯D0) states and is reconstructed through the decay chains D∗ → ... -
Observation of New Baryons in the Ξ−b π + π − and Ξ0bπ + π − Systems
Aaij, Roel; Chobanova, Veronika (American Physical Society, 2023-10-27)[Abstract] The first observation and study of two new baryonic structures in the final state Ξ0bπþπ− and the confirmation of the Ξbð6100Þ− state in the Ξ−b πþπ− decay mode are reported using proton-proton collision data ... -
Observation of the decays B0(s) → Ds1(2536)∓K±
Aaij, Roel; Wang, Zirui; Chobanova, Veronika (Springer, 2023-10-17)[Abstract] This paper reports the observation of the decays B0(s) → Ds1(2536)∓K± using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb−1. The branching ... -
Precision Measurement of CP Violation in the Penguin-Mediated Decay Bs0→ϕϕ
Aaij, Roel; Chobanova, Veronika (American Physical Society, 2023-10-27)[Abstract] A flavor-tagged time-dependent angular analysis of the decay B0s→ ϕϕ is performed using pp collision data collected by the LHCb experiment at the center-of-mass energy of 13 TeV, corresponding to an integrated ...
