SMEFT goes dark: Dark Matter models for four-fermion operators by Ricardo Cepedello, Fabian Esser, Martin Hirsch, Veronica Sanz

“…Abstract We study ultra-violet completions for d = 6 four-fermion operators in the standard model effective field theory (SMEFT), focusing on models that contain cold dark matter candidates. Via a diagrammatic method, we generate systematically lists of possible UV completions, with the aim of providing sets of models, which are complete under certain, well specified assumptions. …”

Modified Newtonian Dynamics in the Milky Way by Famaey, B, Binney, J

“…Both microlensing surveys and radio-frequency observations of gas flow imply that the inner Milky Way is completely dominated by baryons, contrary to the predictions of standard cold dark matter (CDM) cosmology. We investigate the predictions of the Modified Newtonian Dynamics (MOND) formula for the Galaxy given the measured baryon distribution. …”

Prospects for direct dark matter detection in the constrained MSSM by Trotta, R, Ruiz de Austri, R, Roszkowski, L

“…We outline the WIMP dark matter parameter space in the constrained MSSM by performing a comprehensive statistical analysis that compares with experimental data predicted superpartner masses and other collider observables as well as a cold dark matter abundance. We include uncertainties arising from theoretical approximations as well as from residual experimental errors on relevant Standard Model parameters.We present high-probability regions for neutralino dark matter direct detection cross section, and we find that 10(-10)pb less than or similar to sigma(SI)(P) less than or similar to ph for direct WIMP detection (with details slightly dependent on the assumptions made). …”

The Λ and the CDM as Integration Constants by Priidik Gallagher, Tomi Koivisto

“…Notoriously, the two main problems of the standard <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mi mathvariant="sans-serif">Λ</mi></semantics></math></inline-formula>CDM model of cosmology are the cosmological constant <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mi mathvariant="sans-serif">Λ</mi></semantics></math></inline-formula> and the cold dark matter, CDM. This essay shows that both the <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mi mathvariant="sans-serif">Λ</mi></semantics></math></inline-formula> and the CDM arise as integration constants in a careful derivation of Einstein’s equations from first principles in a Lorentz gauge theory. …”

Paradigms and Scenarios for the Dark Matter Phenomenon by Paolo Salucci, Nicola Turini, Chiara di Paolo

“…This brings us to critically focus on the 30-year-old paradigm, that, resting on a priori knowledge of the nature of Dark Matter (DM), has led us to a restricted number of scenarios, especially favouring the collisionless <inline-formula><math display="inline"><semantics><mi mathvariant="sans-serif">Λ</mi></semantics></math></inline-formula> Cold Dark Matter one. Motivated by such observational evidence, we propose to resolve the dark matter mystery by following a new Paradigm: the nature of DM must be guessed/derived by deeply analyzing the properties of the dark and luminous mass distribution at galactic scales. …”

Physics potential of the International Axion Observatory (IAXO)

“…Endowed with a sensitivity to discover axion-like particles (ALPs) with a coupling to photons as small as gaγ∼ 10-12 GeV-1, or to electrons gae∼10-13, IAXO has the potential to find the QCD axion in the 1 meV∼1 eV mass range where it solves the strong CP problem, can account for the cold dark matter of the Universe and be responsible for the anomalous cooling observed in a number of stellar systems. …”

Cuspy Dark-Matter Haloes and the Galaxy by Binney, J, Evans, N

“…We conclude that the cuspy haloes favoured by the Cold Dark Matter cosmology (and its variants) are inconsistent with the observational data on the Galaxy.…”

The Faber–Jackson relation and Fundamental Plane from halo abundance matching by Desmond, H, Wechsler, R

“…In this work, we re-deploy and expand the framework of Desmond &amp; Wechsler to ask whether abundance matching-based Λ-cold dark matter models which have shown success in matching the spatial distribution of galaxies are also capable of explaining key properties of the FJR and FP, including their scatter. …”

First Estimations of Cosmological Parameters From BOOMERANG by Lange, A, Ade, P, Bock, J, Bond, JR, Borrill, J, Boscaleri, A, Coble, K, Crill, B, Bernardis, P, Farese, P, Ferreira, P, Ganga, K, Giacometti, M, Hivon, E, Hristov, V, Iacoangeli, A, Jaffe, A, Martinis, L, Masi, S, Mauskopf, P, Melchiorri, A, Montroy, T, Netterfield, C, Pascale, E, Piacentini, F

“…Within the framework of inflation-motivated adiabatic cold dark matter models, and using only weakly restrictive prior probabilites on the age of the universe and the Hubble expansion parameter $h$, we find that the curvature is consistent with flat and that the primordial fluctuation spectrum is consistent with scale invariant, in agreement with the basic inflation paradigm. …”

Dark matter condensates as highly nonlocal solitons: instability in the Schwarzschild metric and laboratory analog by Ludovica Dieli, Claudio Conti

“…Theories on the bosonic nature of dark matter are a promising alternative to the cold dark matter model. Here we consider a dark matter halo in the state of a Bose–Einstein condensate (BEC), subject to the gravitation of a black hole. …”

A Severe Challenge to the Modified Newtonian Dynamics Phenomenology in Our Galaxy by Man Ho Chan, Ka Chung Law

“…Although it remains controversial regarding MOND as a fundamental theory, MOND phenomenology has been shown to widely apply in different galaxies, which poses challenges to the standard Lambda cold dark matter model. In this article, we derive analytically the galactic rotation curve gradient in the MOND framework and present a rigorous analysis to examine the MOND phenomenology in our Galaxy. …”
