Lepton number violation: seesaw models and their collider tests

Y Cai, T Han, T Li, R Ruiz - Frontiers in Physics, 2018 - frontiersin.org
The Majorana nature of neutrinos is strongly motivated from the theoretical and
phenomenological point of view. A plethora of neutrino mass models, known collectively as …

Same sign versus opposite sign dileptons as a probe of low scale seesaw mechanisms

A Das, PSB Dev, RN Mohapatra - Physical Review D, 2018 - APS
We calculate the ratio R ℓ ℓ of same sign (SS) to opposite sign (OS) dileptons in type I and
generalized inverse seesaw models and show that it can be anywhere between 0 and 1 …

Neutrino jets from high-mass gauge bosons in TeV-scale left-right symmetric models

M Mitra, R Ruiz, DJ Scott, M Spannowsky - Physical Review D, 2016 - APS
We reexamine the discovery potential at hadron colliders of high-mass right-handed (RH)
gauge bosons WR—an inherent ingredient of left-right symmetric models (LRSM). We focus …

Probing right handed neutrinos at the LHeC and lepton colliders using fat jet signatures

A Das, S Jana, S Mandal, S Nandi - Physical Review D, 2019 - APS
The inclusion of heavy neutral leptons (right-handed neutrinos) to the Standard Model (SM)
particle content is one of the best motivated ways to account for the observed neutrino …

Keung-Senjanović process at the LHC: From lepton number violation to displaced vertices to invisible decays

M Nemevšek, F Nesti, G Popara - Physical Review D, 2018 - APS
In the context of left-right symmetry, we revisit the Keung-Senjanović production of right-
handed WR bosons and heavy neutrinos N at high energy colliders. We develop a …

A low-energy perspective on the minimal left-right symmetric model

Long lived light scalars as probe of low scale seesaw models

PSB Dev, RN Mohapatra, Y Zhang - Nuclear Physics B, 2017 - Elsevier
We point out that in generic TeV scale seesaw models for neutrino masses with local B–L
symmetry breaking, there is a phenomenologically allowed range of parameters where the …
