Abstract A class of Z N≥3-symmetric WIMP dark matter models that are characterized by the semi-annihilation into the companion of dark matter has been proposed in ref. [1], providing a mechanism to evade the stringent direct detection constraint. I

Abstract Neutrinoless double beta (0νββ) decay is the most promising way to determine whether neutrinos are Majorana particles. There are many experiments based on different isotopes searching for 0νββ decay. Combining the searches of 0νββ d

Abstract We study the systematic decomposition of the dimension nine neutron-antineutron oscillation operators at tree and one-loop levels. We discuss the topologies’ generation and the assignment of the chiral quarks. The completed lists of the de

Abstract We extend the contents of the standard model (SM) by introducing TeV-scale scalar leptoquarks to generate neutrino masses and explain some current observed deviations from the SM predictions, including the anomalous magnetic moments of charg

We study the neutrinoless double beta decay in the colored Zee-Babu model. We consider three cases of the colored Zee-Babu model with a leptoquark and a diquark introduced. The neutrino masses are generated at two-loop level, and the constraints give

We explore the phenomenology of the Georgi-Machacek model extended with two Higgs doublets and vector fermion doublets invariant under SU(2)L×U(1)Y×Z4×Z2. The Z4 symmetry is broken spontaneously while the imposed Z2 symmetry forbids triplet fields

Rare B meson decays offer an opportunity to probe a light hidden Z′ boson. In this work we explore a new channel Bq→γZ′ (q=d,s) followed by a cascade decay of Z′ into an invisible (neutrino or dark matter) or charged lepton pair ℓ+ℓ− (

We discuss a new class of neutrino mass models generated in two loops, and explore specifically three new physics scenarios: (A) doubly charged scalar, (B) dark matter, and (C) leptoquark and diquark, which are verifiable at the 14 TeV LHC Run-II. We

The inverse seesaw mechanism provides an attractive approach to generate small neutrino mass, which origins from a tiny U(1)L breaking. In this paper, we work in the supersymmetric version of this mechanism, where the singlet-like sneutrino could be
