A bstractThe inclusion of heavy neutral leptons to the Standard Model particle content could provide solutions to many open questions in particle physics and cosmology. The modification of the…
Leptogenesis in an extended seesaw model with U(1) B-L symmetry
- PhysicsJournal of Physics G: Nuclear and Particle Physics
- 2022
We have explored an extended seesaw model accommodating a keV sterile neutrino adopting U(1)B-L symmetry. This model provides a natural platform for achieving resonant leptogenesis to account for…
Majorana neutrinos in same-sign W±W± scattering at the LHC: Breaking the TeV barrier

The WW production cross section measured at the LHC has been consistently exhibiting a mild excess beyond the SM prediction, in both ATLAS and CMS at both 7-TeV and 8-TeV runs. We provide an…
Automated NNLL $$+$$+ NLO resummation for jet-veto cross sections
