Impact of $b \to c$ measurements on $Λ_{b} \to p τ ν ˉ$ decay in $U_{1}$ leptoquark model

Shabana Khan, Neetu Raj Singh Chundawat, Dinesh Kumar

The measurements of several lepton flavor universality (LFU) violating observables in the decays induced by the quark level transition $b \to c τ ν ˉ$ provide an inkling of plausi…

A global analysis of $b \to s ℓℓ$ data in heavy and light $Z^{'}$ models

Ashutosh Kumar Alok, Neetu Raj Singh Chundawat, Shireen Gangal +1

We perform a model-independent global fit to all $b \to s ℓℓ$ data in the light of recent measurements of the lepton flavour universality violating (LFUV) observables $R_{K_…

Road map through the desert with scalars

Ubaldo Cavazos Olivas, Kamila Kowalska, Dinesh Kumar

In the context of the gauge coupling unification, we present a comprehensive analysis of the extensions of the Standard Model with vector-like fermions and scalars. We find 145 mod…

Impact of $b \to s ℓℓ$ anomalies on rare charm decays in non-universal $Z^{'}$ models

Ashutosh Kumar Alok, Neetu Raj Singh Chundawat, Dinesh Kumar

In this work, we study the impact of $b \to s ℓℓ$ , $B_{s} - B_{s} ˉ$ mixing and neutrino trident measurements on observables in decays induced by $c \to u$ transition in th…

New Physics solutions for $b \to c τ ν ˉ$ anomalies after Moriond 2019

Suman Kumbhakar, Ashutosh Kumar Alok, Dinesh Kumar +1

At Moriond 2019, Belle collaboration has announced new measurements on the flavour ratios $R_{D} - R_{D^{*}}$ which are consistent with their Standard Model predictions within $1.2 σ$ .…

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…
