Two is better than one: The U-spin-CP anomaly in charm

Abstract: The recent measurement of the CP-asymmetry in the decay D→K+K− by LHCb, combined with ΔACP, evidences a sizable CP-asymmetry in the decay D→π+π−, which requires a dynamical enhancement of standard [...] violate U-spin and CP and disfavors flavor singlet contributions such as chromomagnetic dipole operators as explanations of the data. We analyze the reach of flavorful Z′ models for charm CP-asymmetries. Models [...] U-spin and isospin breaking, allowing for correlations with D→π0π0 and D+→π+π0 decays with corresponding CP-asymmetries at similar level and sign as D→π+π−, about (1−2)⋅10−3. Experimental and theoretical constraints …

possible to acquire a certificate of participation (2 CP) or a certificate incl. module examination (3 CP). It is not possible to acquire 5 CP by combining a certificate of participation and a module examination [...] certificate of participation (2 CP) (maximum 3 absences). The module examination will take the form of a multiple-choice exam. For the performance incl. module examination, 3 CP are acquired. It is only possible …

A Precise Electron EDM Constraint on CP-odd Heavy-Quark Yukawas

strong bound on the CP-odd Higgs couplings. We point out that this bound receives large QCD corrections, even though it arises from a leptonic observable. We calculate the contribution of CP-odd Higgs couplings [...] Abstract: CP-odd Higgs couplings to bottom and charm quarks arise in many extensions of the standard model and are of potential interest for electroweak baryogenesis. These couplings induce a contribution …

second analysis presented is the measurement of CP violation in BdToDstDst decays. As the final state is a mixture of CP-even and CP-odd states, the CP observable S(D*+D*-) is diluted. Therefore, an angular …

an integrated luminosity of 6fb^−1 . A time-dependent measurement of the CP asymmetry arising in decays of neutral B mesons to CP-invariant final states is performed in three decay channels: B→J/ψ(→μ+μ-)KS [...] AV-Raum + ZOOM This thesis presents CP-violation measurements conducted with data recorded by the LHCb detector during the Run 2 data-taking phase of the LHC. The size of the data set corresponds to an [...] measurement of the quantity S to date. The parameter S is related to the CKM angle β, which parametrizes CP violation in the Standard Model of particle physics. The result is consistent with previous measurements …

Special colloquium: Probing Hidden Physics From Neutrinos to Flavor

CP-03-123 The flavor structure of the Standard Model exhibits a rich and nontrivial pattern. The discovery of neutrino oscillations demonstrates that flavor mixing is not confined to the quark sector. [...] The CP asymmetries observed in hadron decays, including both mesons and baryons, are too small within the Standard Model to account for the observed matter–antimatter asymmetry. Neutrino mixing, however [...] however, offers a potential new source of CP violation and a window into previously unexplored regions of parameter space. By combining searches for novel neutrino signals with precision measurements in the …
