Post-Recombination Fluctuations from a Sequestered Dark Sector
Salvatore Bottaro, Michael Geller, Diego Redigolo +1
We develop a formalism to characterize the imprints of late-time sources of cosmological fluctuations under the sole assumption that the injection occurs on timescales short compar…
MuCol Milestone Report No. 7: Consolidated Parameters
Rebecca Taylor, Antoine Chancé, Dario Augusto Giove +459
This document is comprised of a collection of consolidated parameters for the key parts of the muon collider. These consolidated parameters follow on from the October 2024 Prelimin…
Testing Real WIMPs with CTAO
Matthew Baumgart, Salvatore Bottaro, Diego Redigolo +2
We forecast the reach of the upcoming Cherenkov Telescope Array Observatory (CTAO) to the full set of real representations within the paradigm of minimal dark matter. We employ eff…
The Muon Collider
Carlotta Accettura, Simon Adrian, Rohit Agarwal +450
Muons offer a unique opportunity to build a compact high-energy electroweak collider at the 10 TeV scale. A Muon Collider enables direct access to the underlying simplicity of the…
MuCol Milestone Report No. 5: Preliminary Parameters
Carlotta Accettura, Simon Adrian, Rohit Agarwal +391
This document is comprised of a collection of updated preliminary parameters for the key parts of the muon collider. The updated preliminary parameters follow on from the October 2…
Looking for WIMPs through the neutrino fogs
Itay M. Bloch, Salvatore Bottaro, Diego Redigolo +1
We revisit the expected sensitivity of large-scale xenon detectors to Weakly Interacting Massive Particles (WIMPs). Assuming current primary noise sources can be mitigated, we find…
A GUT Framework for Accidental Composite Dark Matter
Salvatore Bottaro, Roberto Contino, Sonali Verma
We study and classify -GUT completions of accidental composite dark matter models. These theories postulate new vectorlike confining dark color dynamics and give an accident…
From 100 kpc to 10 Gpc: Dark Matter self-interactions before and after DESI
Salvatore Bottaro, Emanuele Castorina, Marco Costa +2
We consider Dark Matter self-interactions mediated by ultralight scalars. We show that effectively massless mediators lead to an enhancement of the matter power spectrum, while hea…
Interim report for the International Muon Collider Collaboration (IMCC)
C. Accettura, S. Adrian, R. Agarwal +383
The International Muon Collider Collaboration (IMCC) [1] was established in 2020 following the recommendations of the European Strategy for Particle Physics (ESPP) and the implemen…
Neutrino emission in cold neutron stars: Bremsstrahlung and modified urca rates reexamined
Salvatore Bottaro, Andrea Caputo, Damiano Fiorillo
Neutrino emission in cold neutron stars is dominated by the modified urca (murca) process and nucleon-nucleon bremsstrahlung. The standard emission rates were provided by Friman an…
Unveiling dark forces with measurements of the Large Scale Structure of the Universe
Salvatore Bottaro, Emanuele Castorina, Marco Costa +2
Cosmology offers opportunities to test Dark Matter independently of its interactions with the Standard Model. We study the imprints of long-range forces acting solely in the dark s…
The Sommerfeld enhancement at NLO and the dark matter unitarity bound
Salvatore Bottaro, Diego Redigolo
We reexamine the consequences of perturbative unitarity on dark matter freeze-out when both Sommerfeld enhancement and bound state formation affect dark matter annihilations. At le…
Towards a Muon Collider
Carlotta Accettura, Dean Adams, Rohit Agarwal +294
A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions a…
Stellar limits on scalars from electron-nucleus bremsstrahlung
Salvatore Bottaro, Andrea Caputo, Georg Raffelt +1
We revisit stellar energy-loss bounds on the Yukawa couplings of baryophilic and leptophilic scalars . The white-dwarf luminosity function yields $g_{\rm B}\lesssi…
Asymmetric Accidental Composite Dark Matter
Salvatore Bottaro, Marco Costa, Oleg Popov
The goal of this work is to find the simplest UV completions of Accidental Composite Dark Matter models that can dynamically generate an asymmetry for the Dark Matter candidate, th…
The last Complex WIMPs standing
Salvatore Bottaro, Dario Buttazzo, Marco Costa +4
We continue the study of weakly interacting massive particles (WIMP) started in [arXiv:2107.09688], focusing on a single complex electroweak -plet with non-zero hypercharge adde…
A Next-Generation Liquid Xenon Observatory for Dark Matter and Neutrino Physics
J. Aalbers, K. Abe, V. Aerne +591
The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leadi…
Closing the window on WIMP Dark Matter
Salvatore Bottaro, Dario Buttazzo, Marco Costa +4
We study scenarios where Dark Matter is a weakly interacting particle (WIMP) embedded in an ElectroWeak multiplet. In particular, we consider real SU(2) representations with zero h…
Asymmetric accidental composite dark matter
Salvatore Bottaro, Marco Costa, Oleg Popov
The goal of this work is to find the simplest UV completion of Accidental Composite Dark Matter Models (ACDM) that can dynamically generate an asymmetry for the DM candidate, the l…
Minimal Dark Matter bound states at future colliders
Salvatore Bottaro, Alessandro Strumia, Natascia Vignaroli
The hypothesis that Dark Matter is one electroweak multiplet leads to predictive candidates with multi-TeV masses that can form electroweak bound states. Bound states with the same…
QCD axion and topological susceptibility in chiral effective Lagrangian models at finite temperature
Salvatore Bottaro, Enrico Meggiolaro
In this work we compute the axion mass and, from this (exploiting a well-known relation), we also derive an expression for the QCD topological susceptibility in the finite-temperat…
