“…In the literature, various mechanisms have been proposed to address these two anomalies simultaneously, e.g., by introducing lepto-quarks [6,7], in models with gauge-extension [8], by introducing new scalar states and fermionic states [9][10][11][12], etc. Here we discuss a minimal setup in which without extending the gauge sector of the SM or without introducing any exotic fermions or lepto-quarks, one could resolve these two anomalies simultaneously.…”

Recent precise determination of the electron anomalous magnetic moment (AMM) adds to the longstanding tension of the muon AMM and together strongly point towards physics beyond the Standard Model (BSM). Here we present a solution to both anomalies via a light scalar that emerges from a second Higgs doublet and resides in the O (10)-MeV to O (1)-GeV mass range. A scalar of this type is subject to a number of various experimental constraints, however, as we show, it can remain sufficiently light by evading all experimental bounds and has the great potential to be discovered in the near-future low-energy experiments. In addition to the light scalar, our theory predicts the existence of a nearly degenerate charged scalar and a pseudoscalar, which have masses of the order of the electroweak scale. This scenario can be tested at the LHC by looking at the novel process → ± ± → ± ± + / via same-sign pair production of charged Higgs bosons. This talk is based on results presented in hep-ph 2003.03386 [1].

“…Vector boson DM candidates have been studied in several other contexts [24][25][26][27][28][29]. The trinification DM differs from most models in this class in that the gauge interactions of the DM in our framework is completely determined in terms of SU(2) L ×U(1) Y gauge couplings.…”

We show how trinification models based on the gauge group SU(3)C× SU(3)L× SU(3)R realized near the TeV scale can provide naturally a variety of dark matter (DM) candidates. These models contain a discrete T parity which may remain unbroken even after spontaneous symmetry breaking. The lightest T-odd particle, which could be a fermion, a scalar, or a gauge boson, can constitute the dark matter of the universe. This framework naturally admits a doublet-singlet fermionic DM, a singlet scalar DM, or a vector boson DM. Here we develop the vector boson DM scenario wherein the DM couples off-diagonally with the usual fermions and vector-like fermions present in the theory. We show consistency of this framework with dark matter relic abundance and direct detection limits as well as LHC constraints. We derive upper limits of 900 GeV on the vector gauge boson DM mass and 4.5 TeV on the vector-like quark masses. We also show the consistency of spontaneous gauge symmetry breaking down to Standard Model times an extra U(1) while preserving the T-parity.
