Massive right-handed neutrinos in $B ˉ \to D^{*} τ X ˉ$ decay

Nilakshi Das, Alakabha Datta, Tejhas Kapoor +2

We explore signatures of a massive right-handed neutrino (RHN) in angular distributions of $B ˉ \to D^{*} (\to D π) τ (\to π ν_{τ}) X ˉ$ decays, where $X$ is an invisible state. W…

Probing Higgs and Top Interactions through the Muon Lens at multi-TeV Muon Colliders

Tisa Biswas, Anindya Datta, Barbara Mele

We investigate the sensitivity of a future 10 TeV muon collider to dimension-6 operators in the Standard Model Effective Field Theory (SMEFT), focusing on Higgs and top quark produ…

Polarisation fractions in $B \to V_{1} V_{2}$ : U-Spin constraints and new physics signatures

Debajyoti Choudhury, Suman Kumbhakar, Anirban Kundu +1

We investigate the decays of $B$ mesons, {\em i.e.}, $B_{d}$ , $B_{s}$ , $B^{+}$ , and their antiparticles, to two light vector mesons ( $B \to V_{1} V_{2}$ ). We use the SU(2) U-spin symmetry, wh…
