Displaced fat-jets and tracks to probe boosted right-handed neutrinos in the $$U(1)_{B-L}$$ U ( 1 ) B - L model

Autor: Rojalin Padhan, Manimala Mitra, Suchita Kulkarni, Frank F. Deppisch

Publikováno v: European Physical Journal C: Particles and Fields, Vol 82, Iss 10, Pp 1-20 (2022)

Abstract We investigate the pair-production of Right-Handed Neutrinos (RHNs) via a $$B-L$$ B - L $$Z'$$ Z ′ boson and present the sensitivity studies of the active-sterile neutrino mixing ( $$|V_{\mu N}|$$ | V μ N | ) at the High-Luminosity run of

Cosmic inflation in minimal $$U(1)_{B-L}$$ U ( 1 ) B - L model: implications for (non) thermal dark matter and leptogenesis

Autor: Debasish Borah, Suruj Jyoti Das, Abhijit Kumar Saha

Publikováno v: European Physical Journal C: Particles and Fields, Vol 81, Iss 2, Pp 1-22 (2021)

Abstract We study the possibility of realising cosmic inflation, dark matter (DM), baryon asymmetry of the universe (BAU) and light neutrino masses in non-supersymmetric minimal gauged $$B-L$$ B - L extension of the standard model with three right ha

$$U(1)_{B-L}$$ U(1)B-L extension of the standard model with $$S_3$$ S3 symmetry

Autor: V. V. Vien, H. N. Long, A. E. Cárcamo Hernández

Publikováno v: European Physical Journal C: Particles and Fields, Vol 80, Iss 8, Pp 1-12 (2020)

Abstract We propose a renormalizable $$B-L$$ B-L Standard Model (SM) extension based on $$S_3$$ S3 symmetry which successfully accommodates the observed fermion mass spectra and flavor mixing patterns as well as the CP violating phases. The small mas

Neutrinophilic two Higgs doublet model with dark matter under an alternative $$U(1)_{B-L}$$ U(1)B-L gauge symmetry

Autor: Takaaki Nomura, Hiroshi Okada

Publikováno v: European Physical Journal C: Particles and Fields, Vol 78, Iss 3, Pp 1-7 (2018)

Abstract We propose a Dirac type active neutrino with rank two mass matrix and a Majorana fermion dark matter candidate with an alternative local $$U(1)_{B-L}$$ U(1)B-L extension of neutrinophilic two Higgs doublet model. Our dark matter candidate ca

Neutrino mass, leptogenesis and FIMP dark matter in a $$\mathrm{U}(1)_{B-L}$$ U ( 1 ) B - L model

Autor: Anirban Biswas, Sandhya Choubey, Sarif Khan

Publikováno v: European Physical Journal C: Particles and Fields, Vol 77, Iss 12, Pp 1-27 (2017)

Abstract The Standard Model (SM) is inadequate to explain the origin of tiny neutrino masses, the dark matter (DM) relic abundance and the baryon asymmetry of the Universe. In this work, to address all three puzzles, we extend the SM by a local U $$(

A model of the matter–antimatter asymmetry and cold dark matter with U(1)B−L⊗U(1)D

Autor: Wei-Min Yang

Publikováno v: Physics Letters B, Vol 762, Iss , Pp 138-144 (2016)

I suggest an effective model between the GUT and the electroweak scale. It only introduces the two symmetries of U(1)B−L and U(1)D besides the SM groups. The two symmetries are individually broken at the reheating temperature of the universe of 101
