Title: Inception of self-interacting dark matter with dark charge conjugation symmetry

Abstract

A new understanding of the stability of self-interacting dark matter is pointed out, based on the simplest spontaneously broken Abelian gauge model with one complex scalar and one Dirac fermion. The key is the imposition of dark charge conjugation symmetry. It allows the possible existence of two stable particles: the Dirac fermion and the vector gauge boson which acts as a light mediator for the former's self-interaction. Since this light mediator does not decay, it avoids the strong cosmological constraints recently obtained for all such models where the light mediator decays into standard-model particles.

Leptonic dark matter with scalar dilepton mediator

Journal Article Ma, Ernest - Modern Physics Letters A

A simple and elegant mechanism is proposed to resolve the problem of having a light scalar mediator for self-interacting dark matter and the resulting disruption to the cosmic microwave background (CMB) at late times by the former’s enhanced Sommerfeld production and decay. The crucial idea is to have Dirac neutrinos with the conservation of U(1) or [Formula: see text] lepton number extended to the dark sector. The simplest scenario consists of scalar or fermion dark matter with unit lepton number accompanied by a light scalar dilepton mediator, which decays to two neutrinos.

New chiral fermions, a new gauge interaction, Dirac neutrinos, and dark matter

Journal Article de Gouvea, Andre ; Hernandez, Daniel - Journal of High Energy Physics (Online)

Here, we propose that all light fermionic degrees of freedom, including the Standard Model (SM) fermions and all possible light beyond-the-standard-model fields, are chiral with respect to some spontaneously broken abelian gauge symmetry. Hypercharge, for example, plays this role for the SM fermions. We introduce a new symmetry, U(1) ν , for all new light fermionic states. Anomaly cancellations mandate the existence of several new fermion fields with nontrivial U(1)_ν charges. We develop a concrete model of this type, for which we show that (i) some fermions remain massless after U(1)_ν breaking — similar to SM neutrinos — and (ii)more »« less

Astrophysical probes of inelastic dark matter with a light mediator

Journal Article Alvarez, Gerardo ; Yu, Hai-Bo - Physical Review D

We consider an inelastic dark matter model, in which a fermion is charged under a broken U(1) gauge symmetry, and introduce a tiny Majorana mass term to split the fermion into two states with the light one being a dark matter candidate. If the gauge boson is light, it can mediate both elastic and inelastic dark matter self-interactions in dark halos, leading to observational consequences. Using a numerical technique based on partial wave analysis, we accurately calculate the elastic and inelastic self-scattering cross sections. We assume a thermal freeze-out scenario and fix the gauge coupling constant using the relic densitymore »« less

Signatures of self-interacting dark matter in the matter power spectrum and the CMB

Journal Article Huo, Ran ; Kaplinghat, Manoj ; Pan, Zhen ; ... - Physics Letters B

We consider a self-interacting dark matter model in which the massive dark photon mediating the self-interaction decays to light dark fermions to avoid over-closing the universe. We find that if the model is constrained to explain the dark matter halos inferred for spiral galaxies and galaxy clusters simultaneously, there is a strong indication that dark matter is produced asymmetrically in the early universe. It also implies the presence of dark radiation, late kinetic decoupling for dark matter, and a suppressed linear power spectrum due to dark acoustic damping. The Lyman-α forest power spectrum measurements put a strong upper limit onmore »« less
