Enhancement of Direct $C P$ asymmetry in $Z^{'}$ models

Shireen Niteen Gangal

We consider $C P$ -violating $Z^{'}$ models to account for the anomalies in $b \to s ℓℓ$ decays. Using the updated constraints from lepton flavor universality (LFU) violating rat…

The role of non-universal $Z$ couplings in explaining the $V_{u s}$ anomaly

Ashutosh Kumar Alok, Amol Dighe, Shireen Gangal +1

The tension among measurements of $V_{u s}$ from different channels, the so-called Cabibbo Angle Anomaly, can be interpreted as a signal of lepton flavor universality (LFU) violatio…

Higgs Production at NNLL $^{'}$ +NNLO using Rapidity Dependent Jet Vetoes

Shireen Gangal, Jonathan R. Gaunt, Frank J. Tackmann +1

The rapidity-dependent jet veto observables $T_{B j}$ and $T_{C j}$ provide a tight jet veto at central rapidity, gradually transitioning to a loose veto at forwa…

Predictions for $B_{s} \to K ˉ^{*} ℓ ℓ$ in non-universal $Z^{'}$ models

Ashutosh Kumar Alok, Amol Dighe, Shireen Gangal +1

The lepton flavor universality violating (LFUV) measurements $R_{K}$ and $R_{K^{*}}$ in $B$ meson decays can be accounted for in non-universal $Z^{'}$ models. We constrain the couplings o…

Probing signatures of beyond standard model physics through $B_{s}^{*} \to μ^{+} μ^{-}$ decay

Jyoti Saini, Dinesh Kumar, Shireen Gangal +1

We perform a model independent analysis to identify new physics operators which can enhance the branching ratio of $B_{s}^{*} \to μ^{+} μ^{-}$ above its Standard Model (SM) predict…

Continuing search for new physics in $b \to s μμ$ decays: two operators at a time

Ashutosh Kumar Alok, Amol Dighe, Shireen Gangal +1

The anomalies in the measurements of observables involving $b \to s μμ$ decays, namely $R_{K}$ , $R_{K^{*}}$ , $P_{5}^{'}$ , and $B_{s}^{ϕ}$ , may be addressed by adding lepton-universality…
