Pseudo-Nambu-Goldstone dark matter connected to Standard Model fermion through the Higgs portal has the property that its direct detection vanishes in the zero momentum transfer limit due to a cancellation mechanism. This feature helps the Pseudo-Nambu-Goldstone dark matter to escape the stringent constraints from direct detection experiments. In this paper we explore new constraints on parameter space of non-zero momentum transfer from the direct detection experiments, and also from the neutron star temperature via the dark matter reheating mechanism.

“…Our knowledge about the dynamics, composition, and history of the Milky Way is intimately connected to the determination of its gravitational potential (Dehnen & Binney 1998;Klypin et al 2002;Widrow et al 2008;Kafle et al 2014;Cole & Binney 2017;McMillan 2017;Nitschai et al 2020;Cautun et al 2020;Li et al 2020). Furthermore, direct and indirect dark matter detection experiments rely on a precise knowledge of how dark matter is distributed in our Galaxy (Stoehr et al 2003;Vogelsberger et al 2009;Klasen et al 2015;Petač 2020;Nobile 2021). The gravitational potential of the Galaxy is often inferred by fitting a stellar number density distribution to data under the assumption of a steady state, either in the solar neighbourhood (McKee et al 2015;Widmark & Monari 2018;Sivertsson et al 2018;Schutz et al 2018;Buch et al 2019;Guo et al 2020;Salomon et al 2020;Li & Widrow 2021) or a more global spatial volume (Cole & Binney 2017;McMillan 2017;Cautun et al 2020;Hattori et al 2020;Petač 2020).…”

Using the method that was developed in the first paper of this series, we measure the vertical gravitational potential of the Galactic disk from the time-varying structure of the phase-space spiral, using data from Gaia as well as supplementary radial velocity information from legacy spectroscopic surveys. For eleven independent data samples, we inferred gravitational potentials that were in good agreement, despite the data samples' varied and substantial selection effects. Using a model for the baryonic matter densities, we inferred a local halo dark matter density of 0.0085 ± 0.0039 M pc −3 = 0.32 ± 0.15 GeV cm −3 . We were also able to place the most stringent constraint to the surface density of a thin dark disk with a scale height ≤ 50 pc: an upper 95 % confidence limit of roughly 5 M pc −2 (compared to previous limit of roughly 10 M pc −2 , given the same scale height). For the inferred halo dark matter density and thin dark disk surface density, the uncertainties are dominated by the baryonic model. With this level of precision, our method is highly competitive with traditional methods that rely on the assumption of a steady state. In a general sense, this illustrates that time-varying dynamical structures are not solely obstacles to dynamical mass measurements, but can also be regarded as assets containing useful information.

“…In the low-energy regime, nonrelativistic EFTs have been discussed, for example in Refs. [47][48][49][50][51][52][53][54][55][56][57], but more focus has been put on the relativistic case. For instance, a complete set of operators of dimension ≤ 6 (written in the broken phase of the electroweak sector) for an EFT containing the SM fields together with a complex scalar DM field in a singlet, doublet or triplet representation is given in Ref.…”

We present an effective field theory describing the relevant interactions of the Standard Model with an electrically neutral particle that can account for the dark matter in the Universe. The possible mediators of these interactions are assumed to be heavy. The dark matter candidates that we consider have spin 0, 1/2 or 1, belong to an electroweak multiplet with arbitrary isospin and hypercharge and their stability at cosmological scales is guaranteed by imposing a Z 2 symmetry. We present the most general framework for describing the interaction of the dark matter with standard particles, and construct a general non-redundant basis of the gauge-invariant operators up to dimension six. The basis includes multiplets with non-vanishing hypercharge, which can also be viable DM candidates. We give two examples illustrating the phenomenological use of such a general effective framework. First, we consider the case of a scalar singlet, provide convenient semi-analytical expressions for the relevant dark matter observables, use present experimental data to set constraints on the Wilson coefficients of the operators, and show how the interplay of different operators can open new allowed windows in the parameter space of the model. Then we study the case of a lepton isodoublet, which involves co-annihilation processes, and we discuss the impact of the operators on the particle mass splitting and direct detection cross sections. These examples highlight the importance of the contribution of the various nonrenormalizable operators, which can even dominate over the gauge interactions in certain cases.
