Lepton flavor violating decays τ → Pl in the U(1) X SSM model

open access: yesJournal of High Energy Physics, 2022
U(1) X SSM is the extension of the minimal supersymmetric standard model (MSSM) and its local gauge group is SU(3) C × SU(2) L × U(1) Y × U(1) X . To obtain this model, three singlet new Higgs superfields and right-handed neutrinos are added to MSSM.

Impact of B→Kνν¯ measurements on beyond the Standard Model theories [PDF]

open access: yesPhysical Review D, 2021
Semileptonic flavor changing neutral current transitions with a pair of neutrinos in the final state are very accurately determined in the standard model (SM) and thus provide an accurate and sensitive probe for physics beyond the SM. Until recently, the

Precision early universe thermodynamics made simple: Neff and neutrino decoupling in the Standard Model and beyond [PDF]

open access: yes, 2020
Precision measurements of the number of effective relativistic neutrino species and the primordial element abundances require accurate theoretical predictions for early Universe observables in the Standard Model and beyond.

SMEFT Constraints on New Physics beyond the Standard Model [PDF]

open access: yesProceedings of The International Conference on Beyond Standard Model: From Theory To Experiment, 2021
The Fermi effective theory of the weak interaction helped identify the structure of the electroweak sector of the Standard Model, and the chiral effective Lagrangian pointed towards QCD as the theory of the strong interactions.

Prospects for beyond Standard Model Higgs boson searches at future LHC runs and other machines [PDF]

open access: yes, 2017
The discovery of the Higgs boson at the LHC opened up a new possibility to obtain a precise understanding of the origin of mass and the structure of the vacuum.

Annihilation signatures of neutron dark decay models in neutron oscillation and proton decay searches

open access: yesJournal of High Energy Physics, 2019
We point out that two models that reconcile the neutron lifetime anomaly via dark decays of the neutron, also predict dark matter-neutron ( χ ¯ $$ \overline{\chi} $$ − n) annihilation that may be observable in neutron-antineutron oscillation and proton ...

Vacuum stability in the Standard Model and beyond [PDF]

open access: yesPhysical Review D
We revisit the stability of the Standard Model vacuum and investigate its quantum effective potential using the highest available orders in perturbation theory and the most accurate determination of input parameters to date. We observe that the stability

Prospects for beyond the Standard Model physics searches at the Deep Underground Neutrino Experiment [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision ...
