Searches for physics beyond the standard model at colliders [PDF]

open access: yesJournal of Physics: Conference Series, 2008
All experimental measurements of particle physics today are beautifully described by the Standard Model. However, there are good reasons to believe that new physics may be just around the corner at the TeV energy scale. This energy range is currently probed by the Tevatron and HERA accelerators and selected results of searches for physics beyond the ...

A left-right mirror symmetric model: common origin of neutrino mass, baryon asymmetry and dark matter

open access: yesJournal of High Energy Physics, 2020
I suggest a left-right mirror symmetric particle model as the natural and aes- thetic extension of the SM. As the left-right mirror symmetry breaking, the tiny neutrino mass is generated by the radiative mechanism, the baryon asymmetry through the lepto-

MeV neutrino dark matter: relic density, lepton flavour violation and electron recoil

open access: yesJournal of High Energy Physics, 2019
Right-handed neutrinos with MeV to GeV mass are very promising candidates for dark matter (DM). Not only can they solve the missing satellite puzzle, the cusp-core problem of inner DM density profiles, and the too-big-to fail problem, i.e.

Beyond Standard Model Physics

open access: yes, 2009
There are many recent results from searches for fundamental new physics using the TeVatron, the SLAC b-factory and HERA. This talk quickly reviewed searches for pair-produced stop, for gauge-mediated SUSY breaking, for Higgs bosons in the MSSM and NMSSM models, for leptoquarks, and v-hadrons.

Heavy stable charged tracks as signatures of non-thermal dark matter at the LHC: a study in some non-supersymmetric scenarios

open access: yesJournal of High Energy Physics, 2017
We consider two theoretical scenarios, each including a ℤ 2-odd sector and leading to an elementary dark matter candidate. The first one is a variant of the Type-III seesaw model where one lepton triplet is ℤ 2-odd, together with a heavy sterile neutrino.

Pseudo-majoron as light mediator of singlet scalar dark matter

open access: yesJournal of High Energy Physics, 2017
In the singlet-triplet majoron model of neutrino mass, lepton number is spontaneously broken. If it is also softly broken, then a naturally light pseudoscalar particle η I exists.

A singlet doublet dark matter model with radiative neutrino masses

open access: yesJournal of High Energy Physics, 2018
We present a detailed study of a combined singlet-doublet scalar and singlet-doublet fermion model for dark matter. These models have only been studied separately in the past. We show that their combination allows for the radiative generation of neutrino
