Long-lived searches of vectorlike lepton and its accompanying scalar at colliders

QH Cao, J Guo, J Liu, Y Luo, XP Wang - Physical Review D, 2024 - APS
Recently, the vectorlike leptons (VLLs) as a simple extension to the standard model (SM)
have attracted widespread attention both in theory and experiments. The present collider …

Interplay of inert doublet and vector-like lepton triplet with displaced vertices at the LHC/FCC and MATHUSLA

P Bandyopadhyay, M Frank, S Parashar… - Journal of High Energy …, 2024 - Springer
A bstract We study the interaction between the inert Higgs doublet (IDM) dark matter and a
vector-like SU (2) triplet lepton (VLL), both of which are Z 2-odd. The vector current of the …

BSM reach of four-top production at the LHC

Anisha, O Atkinson, A Bhardwaj, C Englert, W Naskar… - Physical Review D, 2023 - APS
Many scenarios of beyond the Standard Model (BSM) physics give rise to new top-philic
interactions that can be probed at proton machines such as the Large Hadron Collider …

Indian contributions to LHC theory

S Raychaudhuri - The European Physical Journal Special Topics, 2023 - Springer
Indian scientists began to work on the theoretical aspects of LHC physics from the early
1980s, at the same time when the rest of the world started taking interest in this then …

Doubly charged scalars and vector-like leptons confronting the muon g-2 anomaly and Higgs vacuum stability

N Chakrabarty - The European Physical Journal Plus, 2021 - Springer
The present work introduces new scalar and fermionic degrees of freedom to the Standard
Model. While the scalar sector is augmented by a complex scalar triplet and a doubly …
