Compact Stars as Portals to Extra-Dimensional Dark Matter
Raghuveer Garani, Chris Kouvaris, Michel H. G. Tytgat +1
We investigate hydrostatic configurations of asymmetric dark matter (DM) spheres in scenarios where fermionic DM can propagate into extra spatial dimensions, while Standard Model f…
No room for minimal monopole dark matter
Felix Brümmer, Giacomo Ferrante, Théodore Fischer +1
The magnetic monopole of a dark sector has been advocated as an appealing dark matter candidate. We revisit the computation of the monopole abundance , generated by a thermal…
The Simplest Dark Matter Model at the Edge of Perturbativity
Miguel Escudero, Thomas Hambye
Increasingly sensitive direct detection dark matter experiments are testing important regions of parameter space for WIMP dark matter and pushing many models to the multi-TeV regim…
t-channel dark matter at the LHC -- a whitepaper
Chiara Arina, Benjamin Fuks, Luca Panizzi +67
This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…
Interplay of intrinsic motion of partons and soft gluon emissions in Drell-Yan production studied with PYTHIA
I. Bubanja, H. Jung, N. Raicevic +1
Understanding the intrinsic transverse momentum (intrinsic-) of partons within colliding hadrons, typically modeled with a Gaussian distribution characterized by a specific wi…
Symmetries from outer automorphisms and unorthodox group extensions
Christian Döring, Andreas Trautner
Symmetries play an essential role in the construction and phenomenology of quantum field theories (QFTs). We discuss how to construct symmetries of QFTs by extending minimal "seed"…
Energy-scaling behavior of intrinsic transverse momentum parameters in Drell-Yan simulation
CMS Collaboration
An analysis is presented based on models of the intrinsic transverse momentum (intrinsic ) of partons in nucleons by studying the dilepton transverse momentum in Drel…
Center-of-mass energy dependence of intrinsic- distributions obtained from Drell-Yan production
I. Bubanja, H. Jung, A. Lelek +2
The internal motion of partons inside hadrons has been studied through its impact on very low transverse momentum spectra of Drell-Yan (DY) pairs created in hadron-hadron collision…
Prospects for Heavy Neutral Lepton Searches at Short and Medium Baseline Reactor Experiments
N. van Remortel, M. Colomer Molla, B. Clerbaux +6
Heavy neutrinos with masses in the MeV range can in principle simultaneously explain the light neutrino masses and the origin of baryonic matter in the universe. The strongest cons…
Constraints on metastable superheavy dark matter coupled to sterile neutrinos with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +368
Dark matter particles could be superheavy, provided their lifetime is much longer than the age of the universe. Using the sensitivity of the Pierre Auger Observatory to ultra-high…
Accidentally light scalars from large representations
Felix Brümmer, Giacomo Ferrante, Michele Frigerio +1
In models with spontaneous symmetry breaking by scalar fields in large group representations, we observe that some of the scalar masses can be loop-suppressed with respect to the n…
A forgotten fermion: the hypercharge -3/2 doublet, its phenomenology and connections to dark matter
Rupert Coy
A weak-doublet with hypercharge is one of only a handful of fermions which has a renormalisable interaction with Standard Model fields. This should make it worthy of attenti…
Telling compositeness at a distance with outer automorphisms and CP
Ingolf Bischer, Christian Döring, Andreas Trautner
We investigate charge-parity (CP) and non-CP outer automorphism of groups and the transformation behavior of group representations under them. We identify situations where composit…
A closer look at the seesaw-dark matter correspondence
Rupert Coy, Aritra Gupta
In an earlier work, we showed that in very simple neutrino portal-like extensions of the Standard Model it is possible to achieve a one-to-one correspondence between dark matter ph…
The CMSSM Survives Planck, the LHC, LUX-ZEPLIN, Fermi-LAT, H.E.S.S. and IceCube
John Ellis, Keith A. Olive, Vassilis C. Spanos +1
We revisit the viability of the CMSSM, searching for regions of parameter space that yield a neutralino dark matter density compatible with Planck measurements, as well as LHC cons…
A new life for sterile neutrino dark matter after the pandemic
Torsten Bringmann, Paul Frederik Depta, Marco Hufnagel +3
We propose a novel mechanism to generate sterile neutrinos in the early Universe, by converting ordinary neutrinos in scattering processes . After init…
Freeze-in and freeze-out of sterile neutrino dark matter
Rupert Coy, Michael A. Schmidt
A sterile neutrino with a keV-scale mass is a compelling dark matter candidate. We propose a new production mechanism involving the decay and annihilation of a complex scalar singl…
The Present and Future Status of Heavy Neutral Leptons
Asli M. Abdullahi, Pablo Barham Alzas, Brian Batell +42
The existence of non-zero neutrino masses points to the likely existence of multiple SM neutral fermions. When such states are heavy enough that they cannot be produced in oscillat…
Neutrino forces and the Sommerfeld enhancement
Rupert Coy, Xun-Jie Xu, Bingrong Yu
The Sommerfeld enhancement plays an important role in dark matter (DM) physics, and can significantly enhance the annihilation cross section of non-relativistic DM particles. In th…
Inelastic Dirac Dark Matter
Anastasiia Filimonova, Sam Junius, Laura Lopez Honorez +1
Feebly interacting thermal relics are promising dark matter candidates. Among them, scenarios of inelastic Dark Matter evade direct detection by suppressed elastic scattering off a…
Cosmological constraints on the decay of heavy relics into neutrinos
Thomas Hambye, Marco Hufnagel, Matteo Lucca
A massive particle decaying into neutrinos in the early Universe is known to be less constrained than if it was decaying into other standard model particles. However, even if the d…
Dark matter produced from neutrinos
Marco Hufnagel, Xun-Jie Xu
In the presence of interactions between neutrinos and dark matter (DM), DM can potentially be produced via freeze-in from the neutrino sector. We investigate the implications of su…
Supercool Composite Dark Matter Beyond 100 TeV
Iason Baldes, Yann Gouttenoire, Filippo Sala +1
Dark Matter could be a composite state of a confining sector with an approximate scale symmetry. We consider the case where the associated pseudo-Goldstone boson, the dilaton, medi…
Effective comparison of neutrino-mass models
Rupert Coy, Michele Frigerio
New physics in the lepton sector may account for neutrino masses, affect electroweak precision observables, induce charged-lepton flavour violation, and shift dipole moments. The l…
