Polarisation fractions in : U-Spin constraints and new physics signatures

Debajyoti Choudhury, Suman Kumbhakar, Anirban Kundu +1

We investigate the decays of mesons, {\em i.e.}, , , , and their antiparticles, to two light vector mesons (). We use the SU(2) U-spin symmetry, wh…

Novel and Updated Bounds on Flavor-Violating Z Interactions in the Quark Sector

Fayez Abu-Ajamieh, Amine Ahriche, Suman Kumbhakar +1

We derive bounds on the flavor-violating (FV) couplings of the boson to quarks and present future sensitivity projections. Our analysis shows that the current bounds on the FV…

Anomalies in Hadronic Decays: an Update

Bhubanjyoti Bhattacharya, Marianne Bouchard, Luke Hudy +3

Recently, decays (, ) were analyzed under the assumption of flavor SU(3) symmetry (SU(3)). Although the individual fits to $…

Improved Bounds and Global Fit of Flavor-Violating Charged Lepton Yukawa Couplings post LHC

Fayez Abu-Ajamieh, Suman Kumbhakar, Ratan Sarkar +1

Higgs couplings to charged leptons form an important measurement to understand not only the Standard Model (SM), but also physics Beyond Standard Models (BSM). In this work, we upd…

Anomalies in Hadronic Decays

Raphaël Berthiaume, Bhubanjyoti Bhattacharya, Rida Boumris +3

In this paper, we perform fits to decays, where and the pseudoscalar , under the assumption of flavor SU(3) symmetry [SU(3)]…
