“…On the one hand, a non-relativistic effective field theory (NREFT) [33][34][35] based on the lowest-order operators that can describe the coupling of a WIMP to a nucleon. The NREFT approach proposes a set of one-body operators, considered in recent experimental analyses [36][37][38][39]. On the other hand, an organization based on chiral effective field theory (ChEFT) [40][41][42], a low-energy effective theory of quantum chromodynamics (QCD) that preserves the QCD symmetries, in particular capturing the important role played by pions at low energies.…”

Nuclear structure factors for general spin-independent WIMP-nucleus scattering

We present nuclear structure factors that describe the generalized spin-independent coupling of weakly interacting massive particles (WIMPs) to nuclei. Our results are based on state-of-the-art nuclear structure calculations using the large-scale nuclear shell model. Starting from quark-and gluon-level operators, we consider all possible coherently enhanced couplings of spin-1/2 and spin-0 WIMPs to one and two nucleons up to third order in chiral effective field theory. This includes a comprehensive discussion of the structure factors corresponding to the leading two-nucleon currents covering, for the first time, the contribution of spin-2 operators. We provide results for the most relevant nuclear targets considered in present and planned dark matter direct detection experiments: fluorine, silicon, argon, and germanium, complementing our previous work on xenon. All results are also publicly available in a Python

“…In scenarios where this leading contribution vanishes or is strongly suppressed, other search channels become important. Experimentally, this aspect is addressed by dedicated analyses, e.g., for spin-dependent (SD) WIMPnucleon interactions [15][16][17][18][19], nonrelativistic effective field theory (NREFT) operators [20][21][22][23], or generically q-suppressed responses [24]. Contributions beyond the widely considered SD channel include subleading NREFT operators [25][26][27].…”

Weakly interacting massive particles (WIMPs) may interact with a virtual pion that is exchanged between nucleons. This interaction channel is important to consider in models where the spin-independent isoscalar channel is suppressed. Using data from the first science run of the LUX-ZEPLIN dark matter experiment, containing 60 live days of data in a 5.5 tonne fiducial mass of liquid xenon, we report the results on a search for WIMP-pion interactions. We observe no significant excess and set an upper limit of 1.5 × 10 −46 cm 2 at a 90% confidence level for a WIMP mass of 33 GeV/c 2 for this interaction.

“…The effective method is these low mass regions is to measure electron recoils. Experiments like SENSEI [145], XENON-10 [146], XENON-100 [147], SuperCDMS [148] and DarkSide-50 [149] have measured dark matter electron scattering 13 For even lower masses, CRESST-III [144] has better sensitivity, however, we have not explored the region MDM 1 GeV.…”

In this work we have considered a minimal extension of Standard Model by a local U(1) gauge group in order to accommodate a stable (fermionic) Dark Matter (DM) candidate. We have focussed on parameter regions where DM possesses adequate selfinteraction, owing to the presence of a light scalar mediator (the dark Higgs), alleviating some of the tensions in the small-scale structures. We have studied the scenario in the light of a variety of data, mostly from dark matter direct searches, collider searches and flavor physics experiments, with an attempt to constrain the interactions of the standard model (SM) particles with the ones in the Dark Sector (DS). Assuming a small gauge kinetic mixing parameter, we find that for rather heavy DM the most stringent bound on the mixing angle of the Dark Higgs with the SM Higgs boson comes from dark matter direct detection experiments, while for lighter DM, LHC constraints become more relevant. Note that, due to the presence of very light mediators, the effective operator approach to the direct detection is inapplicable here and these constraints have been re-evaluated for our scenario. In addition, we find that the smallness of the relevant portal couplings, as dictated by data, critically suppress the viability of DM production by the standard "freeze-out" mechanism in such simplified scenarios. In particular, the viable DM masses are O(2) GeV i.e. in the regions where direct detection limits tend to become weak. For heavier DM with large self-interactions, we hence conclude that non-thermal production mechanisms are favored. Lastly, future collider reach of such a simplified scenario has also been studied in detail.The evidence for existence of non-relativistic non-luminous Dark Matter (DM) has been overwhelming. Several astrophysical and cosmological observations have indicated the presence of DM [1]. Within the paradigm of the standard model of cosmology (ΛCDM) recent measurements of the Cosmic Microwave Background Radiation (CMBR) estimated that about 26% of the energy budget of our Universe consists of DM [2, 3]. 1 CMBR, together with Big Bang Nucleosynthesis (BBN) requires DM to be non-baryonic. Astro-physical objects, especially primordial black holes (PBHs) have been considered as DM candidates. While such PBHs, for certain windows of mass 2 can account for the entire energy budget of DM, it has been shown that adequate production of PBHs after (single-field slow-roll) inflation can be difficult [7,8]. However, the standard model (SM) of particle physics, does not incorporate any suitable DM candidate. Various extensions of the SM has been considered in the literature [9,10]. A generic aspect in DM models concerns about the stability of DM. Constraints from structure formation, indirect searches [11][12][13] and CMB [14] require DM to be very long-lived (life-time τ 10 26 s depending on the decay modes). The simplest models introduce a global symmetry to prevent the decay of DM. However, it has been argued that such global symmetries may be broken due to gravitational...
