Flavour anomalies after the RK∗ measurement
The LHCb measurement of the μ/e ratio RK∗ indicates a deficit with respect to the Standard Model prediction, supporting earlier hints of lepton universality violation observed in the RK ratio. We show that the RK and RK∗ ratios alone constrain the chiralities of the states contributing to these anomalies, and we find deviations from the Standard Model at the 4σ level. This conclusion is further...
متن کاملAnomalies and WZW-term of two-flavour QCD
The U(2)R×U(2)L symmetry of QCD with two massless flavours is subject to anomalies which affect correlation functions involving the singlet currents Aμ or V 0 μ . These are relevant for πγ-interactions, because – for two flavours – the electromagnetic current contains a singlet piece. We give the effective Lagrangian required for the corresponding low energy analysis to next-to-leading order, w...
متن کاملFlavour structure , flavour symmetry and supersymmetry ∗
One of the most obscure sides of particle physics concerns the fermion flavor structure. This is a complex problem with different aspects questioning the origin of the mass spectrum and mixing pattern of quarks and leptons (including neutrinos) and CP-violation, as well as the suppression of flavor changing (FC) neutral currents, the strong CP-problem, etc. [1]. Presently, thanks to the new dat...
متن کاملEffects of hunger state on flavour pleasantness conditioning at home: flavour-nutrient learning vs. flavour-flavour learning.
UNLABELLED This study examined acquired liking of flavour preferences through flavour-flavour and flavour-nutrient learning under hungry or sated conditions in a naturalistic setting. Each participant consumed one of three versions of a test drink at home either before lunch or after lunch: minimally sweetened ( CONTROL 3% sucrose, 40 kcal), artificially sweetened (3% sucrose 40 kcal plus art...
متن کاملSingle-flavour and two-flavour pairing in three-flavour quark matter
We study single-flavour quark pairing (“self-pairing”) in colour-superconducting phases of quark matter, paying particular attention to the difference between scenarios where all three flavours undergo single-flavour pairing, and scenarios where two flavours pair with each other (“2SC” pairing) and the remaining flavour self-pairs. We perform our calculations in the mean field approximation usi...
