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…
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: 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 $Δ…
Uniting Low-energy Semileptonic and Hadronic Anomalies within SMEFT
Alakabha Datta, Jacky Kumar, Suman Kumbhakar +1
Two categories of four-fermion SMEFT operators are semileptonic (two quarks and two leptons) and hadronic (four quarks). At tree level, an operator of a given category contributes…
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)].…
