“…Experimentally, with the aim of testing as many scenarios as possible [39], a complementary program has been developed to test the possible existence of MeV-scale dark matter particles and potential companions Beyond the Standard Model (BSM) [14][15][16][17]. Light dark matter particles and their potential mediators with the dark sector have been searched for at particle colliders [40][41][42][43][44][45][46][47], beam dump experiments [48][49][50], neutrino experiments [51][52][53][54][55][56], neutrino telescopes [57][58][59], as well as in direct [60][61][62][63][64][65][66][67] and indirect [68][69][70] dark matter detection experiments. Searches for light BSM species are not only carried out in terrestrial experiments, but a variety of astrophysical [71][72][73][74][75][76] and cosmological [77][78][79]…”

New light states thermally coupled to the Standard Model plasma alter the expansion history of the Universe and impact the synthesis of the primordial light elements. In this work, we carry out an exhaustive and precise analysis of the implications of MeV-scale BSM particles in Big Bang Nucleosynthesis (BBN) and for Cosmic Microwave Background (CMB) observations. We find that BBN observations set a lower bound on the thermal dark matter mass of mχ > 0.4 MeV at 2σ. This bound is independent of the spin and number of internal degrees of freedom of the particle, of the annihilation being s-wave or p-wave, and of the annihilation final state. Furthermore, we show that current BBN plus CMB observations constrain purely electrophilic and neutrinophilic BSM species to have a mass, mχ > 3.7 MeV at 2σ. We explore the reach of future BBN measurements and show that upcoming CMB missions should improve the bounds on light BSM thermal states to mχ > (10 − 15) MeV. Finally, we demonstrate that very light BSM species thermally coupled to the SM plasma are highly disfavoured by current cosmological observations. S nashwan.sabti@kcl.ac.uk

The measurement of an annual modulation in the event rate of direct dark matter detection experiments is a powerful tool for dark matter discovery. Indeed, several experiments have already claimed such a discovery in the past decade. While most of them have later revoked their conclusions, and others have found potentially contradictory results, one still stands today. This paper explains the potential as well as the challenges of annual modulation measurements, and gives an overview on past, present and future direct detection experiments.

“…Solid-state silicon detectors, such as SENSEI [9,10], DAMIC [11], and SuperCDMS [12] have also demonstrated their potential in the region for sub-GeV light dark matter detection. More recently, constraints on sub-GeV dark matter from electronic recoils were further improved by the XENON1T [13] experiment. The main factors currently limiting the sensitivity of liquid xenon detectors are previously-ignored background sources at the level of single or a few electrons.…”

Two-phase noble liquid detectors, with large target masses and effective background reduction, are currently leading the dark matter direct detection for WIMP masses above a few GeV. Due to their sensitivity to single ionized electron signals, these detectors were shown to also have strong constraints for sub-GeV dark matter via their scattering on electrons. In fact, the most stringent direct detection constraints for sub-GeV dark matter down to as low as 5 MeV come from noble liquid detectors, namely XENON10, DarkSide-50, XENON100 and XENON1T, although these experiments still suffer from high background at single or a few electron level. LBECA is a planned 100-kg scale liquid xenon detector with significant reduction of the single and a few electron background. The experiment will improve the sensitivity to sub-GeV dark matter by three orders of magnitude compared to the current best constraints.
