This paper presents the inaugural investigation of beyond the Standard Model (BSM) radiation processes, framed as a generalized, process- and model-independent parton shower algorithm within Herwig 7, based on direct translations of Universal FeynRul

The wealth of experimental data collected at laboratory experiments suggests that there is some scale separation between the Standard Model (SM) and phenomena beyond the SM (BSM). New phenomena can manifest itself as small corrections to SM predictio

We provide an overview of the status of Monte-Carlo event generators for high-energy particle physics. Guided by the experimental needs and requirements, we highlight areas of active development, and opportunities for future improvements. Particular

Electroweak Radiative Corrections in Precision LHC Measurements of $W^\pm/Z^0$+jets

Autor: Darvishi, Neda, Masouminia, M. R.

Publikováno v: Nucl.Phys.B 985 (2022) 116025

We calculate the fiducial and differential $W^{\pm}/Z^0+jet(s)$ production cross-sections in the presence of electroweak (EW) corrections through virtual loop contributions to the matrix elements (MEs) of the processes and real partonic cascade emiss

Maximally Symmetric Three Higgs Doublet Model

Autor: Darvishi, Neda, Masouminia, M. R., Pilaftsis, Apostolos

Publikováno v: Phys. Rev. D 104, 115017 (2021)

We consider the general Three-Higgs Doublet Model (3HDM) and identify all limits that lead to exact SM alignment. After discussing the underlying symmetries that can naturally enforce such an alignment, we focus on the most economic setting, called h
