Constraining anomalous $Wtb$ and related SMEFT couplings using low-energy and electroweak precision observables

Subhajit Kala, Lipika Kolay, Lopamudra Mukherjee +1

We investigate constraints on couplings of Standard Model effective field theory (SMEFT) operators contributing to $Wtb$ effective vertex at tree level. We study the one-loop level…
