Multi-lepton probes of new physics and lepton-universality in top-quark interactions

Y Afik, S Bar-Shalom, K Pal, A Soni, J Wudka - Nuclear Physics B, 2022 - Elsevier
We explore the sensitivity to new physics (NP) in the associated production of top-quarks
with leptons pp→ tt¯ ℓ+ ℓ−, which leads to the multi-leptons signals pp→ n ℓ+ jets+ E̸ T …

Asymmetry in flavour changing electromagnetic transitions of vector-like quarks

S Balaji - Journal of High Energy Physics, 2022 - Springer
A bstract Vector-like quarks have been of interest for a plethora of experimentally motivated
reasons and have come under increased investigation recently due to their inclusion to the …

Single top production via FCNC couplings at an collider with center-of-mass energy GeV

MA Arroyo-Urena, JL Díaz-Cruz, R Gaitan… - The European Physical …, 2022 - Springer
Aspects of top quark physics can be studied at a future Circular Electron-Positron Collider. In
particular, flavor-changing neutral current interactions (FCNC) of the top quark can be …
