Strong thermal SO(10)-inspired leptogenesis in the light of recent results from long-baseline neutrino experiments

open access: yesJournal of High Energy Physics, 2018
We confront recent experimental results on neutrino mixing parameters with the requirements from strong thermal SO(10)-inspired leptogenesis, where the asymmetry is produced from next-to-lightest right-handed neutrinos N 2 independently of the initial ...

Beyond the Desert: Tevatron and LHC Results on Searches for Physics Beyond the Standard Model [PDF]

open access: yesarXiv, 2011
This is a brief and limited review of searches for physics beyond the Standard Model from the ATLAS, CDF, CMS and D0 experiments, as of the end of July 2011. Priority is given to the most recent results and to those with the largest integrated luminosity analyzed.

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.

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.

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-

Status of the Standard Model [PDF]

open access: yesarXiv, 1998
We review the experimental and theoretical status of the standard electroweak theory, and its fundamental parameters. We obtain the global best fit result for the Standard Model Higgs boson of M_H = 107^{+67}_{-45} GeV, and find the 95% upper limit of 255 GeV. Parameters describing physics beyond the Standard Model are discussed as well.

Beyond the Standard Model physics at the Tevatron

open access: yesJournal of Physics: Conference Series, 2006
The purpose of this lecture is to provide an overview of the analyses currently pursued by the Tevatron collaborations in the search for processes beyond the Standard Model. The focus has been put on Supersymmetry and - wherever possible - a pedagogical approach has been followed in presenting the analyses.

B Factories

open access: yes, 2012
The B factories were constructed with a very specific purpose in mind: to test the Cabibbo-Kobayashi-Maskawa description of quark mixing and CP violation in the Standard Model of particle physics. The goals of testing this part of the Standard Model were

Some Physics Beyond the Standard Model at Gamma Gamma Colliders [PDF]

open access: yesarXiv, 2004
In this talk, I describe a few interesting physics beyond the standard model that are quite unique for $\gamma\gamma$ collisions, including large extra dimension model (ADD), warped extra dimension model (Randall-Sundrum) model, universal extra dimension model, as well as techni-pions of technicolor models.

Inverse seesaw and dark matter in a gauged B − L extension with flavour symmetry

open access: yesJournal of High Energy Physics, 2018
We propose a model which generates neutrino masses by the inverse seesaw mechanism, provides a viable dark matter candidate and explains the muon (g−2) anomaly.
