Top-quark forward-backward asymmetry from a color-octet t-channel resonance
(American Physical Society, 2014-05-09)
We consider new physics contributions to the top-quark forward-backward asymmetry from a neutral V-8(0) or charged V-8(+) color-octet vector exchanged in the t channel. We study the phenomenological constraints on these ...
LHC constraints on W′, Z′ that couple mainly to third generation fermions
(Springer Nature, 2020-11-03)
We use the results of CMS and ATLAS searches for resonances that decay to tau nu or tb and tau(+)tau(-) or t (t) over bar final states to constrain the parameters of non-universal W' and Z' gauge bosons that couple ...
Color-octet scalar decays to a gluon and an electroweak gauge boson in the Manohar-Wise model
(American Physical Society, 2020-12-28)
We present one loop results for the amplitudes giving rise to couplings between a color octet scalar, a gluon, and an electroweak gauge boson. These amplitudes could signal new physics in( )gamma jet, Z jet and W jet ...
Investigating the violation of charge-parity symmetry through top-quark chromoelectric dipole moments by using machine learning techniques
(Jagiellonian University, 2023)
There are a number of studies in the literature on the search for Charge- Parity (CP) violating signals in top-quark productions at the LHC. In most of these studies, ChromoMagnetic Dipole Moments (CMDM) and ChromoElectric ...
