Probing anomalous quartic gauge couplings via vector boson scattering at the same-sign muon collider
Lopamudra Mukherjee, Abhik Sarkar
The measurement of quartic gauge couplings (QGCs) provides a crucial test of the non-Abelian gauge structure of the Standard Model and offers sensitivity to new physics effects. In…
Constraining anomalous 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 effective vertex at tree level. We study the one-loop level…
Is Dark Matter the origin of the excess at Belle II?
Lorenzo Calibbi, Tong Li, Lopamudra Mukherjee +1
We present two models of dark matter (DM) that can provide a natural explanation of the excess of events with respect to the Standard Model (SM) pr…
Probing ALP Lepton Flavour Violation at TRISTAN
Lorenzo Calibbi, Tong Li, Lopamudra Mukherjee +1
Axion-like particles (ALPs) with lepton flavour violating (LFV) interactions are predicted within a wide range of flavoured ALP models. The proposed TRISTAN high-energy $e^-μ^…
