Exotic Leptonic solutions to observed anomalies in lepton universality observables and more

Lobsang Dhargyal

In this talk I will present the work that we did in \cite{1}\cite{2}\cite{3}\cite{4}\cite{5} related to observed lepton universality violation by Babar, Belle and LHCb in R($D^{(*)…

Phenomenological consequences of introducing new fermions with exotic charges to $R (K^{(*)})$ , muon (g-2), the primordial Lithium problem, and dark matter

Lobsang Dhargyal

In this work we show that, by introducing two $S U (3)_{c} \times S U (2)_{L}$ singlet right handed fermions carrying opposite $U (1)_{Y}$ charges and while their left handed counterpart…

Search for an exotic-leptonic solution to observed anomalies in lepton universality observables in B decays and more

Lobsang Dhargyal

In this work we extend the SM by introducing only exotic scalars and leptons and show that within the reasonable error limits, both the observed anomalies in $R (D^{(*)})$ and $R_{K…

Implications of a vector-like lepton doublet and scalar Leptoquark on $R (D^{(*)})$

Lobsang Dhargyal, Santosh Kumar Rai

We study the phenomenological constraints and consequences in the flavor sector, of introducing a new fourth generation $Z_{2}$ odd vector-like lepton doublet along with…

$R (D^{(*)})$ and $B r (B \to τ ν_{τ})$ in a Flipped/Lepton-Specific 2HDM with anomalously enhanced charged Higgs coupling to $τ$ /b

Lobsang Dhargyal

Babar, Belle and recently LHCb has reported an excess in the measurements of $R (D^{*})$ , $R (D)$ and $B r (B \to τ ν_{τ})$ than expected from SM, a possible signature…
