Non-Abelian vector dark matter and lepton g-2

چکیده

The mystery of dark matter remains an unsettled problem particle physics. On top that, experiments show a persistent contention the muon anomalous magnetic moment (AMM) relative to Standard Model (SM) prediction. In this work, we consider possibility extending SM with non-Abelian gauge symmetry $SU(2)_X$, under which leptons transform non-trivially. receive corrections their AMMs right order via one-loop processes mediated by beyond (BSM) fermions required cancel anomalies, and BSM bosons that play role matter. We simultaneous explanation AMM along reproducing correct relic abundance allows rather narrow range 0.5 - 2 TeV mass, consistent current experimental constraints. However, concurrent description also includes electron is challenging in set-up.

Lepton Portal dark matter

We study a class of simplified dark matter models in which dark matter couples directly with a mediator and a charged lepton. This class of Lepton Portal dark matter models has very rich phenomenology: it has loop generated dark matter electromagnetic moments that generate a direct detection signal; it contributes to indirect detection in the cosmic positron flux via dark matter annihilation; i...

Vector Unparticle Contributions to Lepton G-2

The generic unparticle propagator may be modified in two ways. Breaking the conformal symmetry effectively adds a mass term to the propagator, while considering vacuum polarization corrections adds a width-like term. Both of these modifications result naturally from the coupling of the unparticle to standard model (SM) fields. We explore how these modifications to the propagator affect the calc...

Emergent Dark Matter, Baryon, and Lepton Numbers

We present a new mechanism for transferring a pre-existing lepton or baryon asymmetry to a dark matter asymmetry that relies on mass mixing which is dynamically induced in the early universe. Such mixing can succeed with only generic scales and operators and can give rise to distinctive relationships between the asymmetries in the two sectors. The mixing eliminates the need for the type of addi...

Self-interacting dark matter from a non-Abelian hidden sector

There is strong evidence in favor of the idea that dark matter is self interacting, with the cross section-tomass ratio σ=m ∼ 1 cm=g ∼ 1 barn=GeV. We show that viable models of dark matter with this large cross section are straightforwardly realized with non-Abelian hidden sectors. In the simplest of such models, the hidden sector is a pure gauge theory, and the dark matter is composed of hidde...

Lepton Jets from Radiating Dark Matter

The idea that dark matter forms part of a larger dark sector is very intriguing, given the high degree of complexity of the visible sector. In this paper, we discuss lepton jets as a promising signature of an extended dark sector. As a simple toy model, we consider an O(GeV) DM fermion coupled to a new U(1)′ gauge boson (dark photon) with a mass of order GeV and kinetically mixed with the Stand...
