The composition of Dark Matter (DM) remains an important open question. The current data do not distinguish between single-and multi-component DM, while in theory constructions it is often assumed that DM is composed of a single field. In this work, we study a hidden sector which naturally entails multicomponent DM consisting of spin-1 and spin-0 states. This UV complete set-up is based on SU(3) hidden gauge symmetry with the minimal scalar field content to break it spontaneously. The presence of multiple DM components is a result of a residual Z 2 × Z 2 symmetry which is part of an unbroken global U(1) × Z 2 inherent in the Yang-Mills systems. We find that the model exhibits various parametric regimes with drastically different DM detection prospects. In particular, we find that the direct detection cross section is much suppressed in large regions of parameter space as long as the Standard Model Higgs mixes predominantly with a single scalar from the hidden sector. The resulting scattering rate is often beyond the level of sensitivity of XENON1T, while still being consistent with the thermal WIMP paradigm.

We consider cases where the dark matter-nucleon interaction is naturally suppressed. We explicitly show that by extending the standard model scalar sector by a number of singlets, can lead to a vanishing direct detection cross section, if some softly broken symmetries are imposed in the dark sector. In particular, it is shown that if said symmetries are SU (2) (SU (N )) and U (1) × S N , then the resulting pseudo-Nambu-Goldstone bosons can constitute the dark matter of the Universe, while naturally explaining the missing signal in nuclear recoil experiments. * email: dimitrios.karamitros@ncbj.gov.pl 1 By doing this, the DM annihilation and nucleon interaction are not correlated, in contrast to what one would expect from the dimensional argument above.2 However, this could change soon as the effort for detection of light DM intensifies [23][24][25][26][27][28][29].

“…Though a single component DM is a very minimal and predictive scenario to begin with, a richer dark sector may in fact be natural given the complicated visible sector. There have been several proposals for multi-component WIMP dark matter during last few years, some of which can be found in [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]. Going from single component to multi-component DM sector can significantly alter the direct as well as indirect detection rates for DM.…”

Type III seesaw for neutrino masses in U(1)B−L model with multi-component dark matter

We propose a B − L gauged extension of the Standard Model where light neutrino masses arise from type III seesaw mechanism. Unlike the minimal B −L model with three right handed neutrinos having unit lepton number each, the model with three fermion triplets is however not anomaly free. We show that the leftover triangle anomalies can be cancelled by two neutral Dirac fermions having fractional B − L charges, both of which are naturally stable by virtue of a remnant Z 2 × Z 2 symmetry, naturally leading to a two component dark matter scenario without any ad-hoc symmetries. We constrain the model from all relevant phenomenological constraints including dark matter properties. Light neutrino mass and collider prospects are also discussed briefly. Due to additional neutral gauge bosons, the fermion triplets in type III seesaw can have enhanced production cross section in collider experiment.
