Dark Matter spikes around Sgr A* in -rays
Shyam Balaji, Divya Sachdeva, Filippo Sala +1
We use H.E.S.S. -ray observations of Sgr A* to derive novel limits on the Dark Matter (DM) annihilation cross-section. We quantify their dependence on uncertainties i) in the DM…
Hot and heavy dark matter from a weak scale phase transition
Iason Baldes, Yann Gouttenoire, Filippo Sala
We point out that dark matter which is produced non-adiabatically in a phase transition (PT) with fast bubble walls receives a boost in velocity which leads to long free-streaming…
The physics case of a 3 TeV muon collider stage
Jorge De Blas, Dario Buttazzo, Rodolfo Capdevilla +131
In the path towards a muon collider with center of mass energy of 10 TeV or more, a stage at 3 TeV emerges as an appealing option. Reviewing the physics potential of such muon coll…
Muon Collider Physics Summary
Chiara Aimè, Aram Apyan, Mohammed Attia Mahmoud +122
The perspective of designing muon colliders with high energy and luminosity, which is being investigated by the International Muon Collider Collaboration, has triggered a growing i…
Friction pressure on relativistic bubble walls
Yann Gouttenoire, Ryusuke Jinno, Filippo Sala
During a cosmological first-order phase transition, particles of the plasma crossing the bubble walls can radiate a gauge boson. The resulting pressure cannot be computed perturbat…
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…
The Muon Smasher's Guide
Hind Al Ali, Nima Arkani-Hamed, Ian Banta +31
We lay out a comprehensive physics case for a future high-energy muon collider, exploring a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the advan…
Neutrino experiments probe hadrophilic light dark matter
Yohei Ema, Filippo Sala, Ryosuke Sato
We use Super-K data to place new strong limits on interactions of sub-GeV Dark Matter (DM) with nuclei, that rely on the DM flux inevitably induced by cosmic-ray upscatterings. We…
Dark matter models for the 511 keV galactic line predict keV electron recoils on Earth
Yohei Ema, Filippo Sala, Ryosuke Sato
We propose models of Dark Matter that account for the 511 keV photon emission from the Galactic Centre, compatibly with experimental constraints and theoretical consistency, and wh…
String Fragmentation in Supercooled Confinement and Implications for Dark Matter
Iason Baldes, Yann Gouttenoire, Filippo Sala
A strongly-coupled sector can feature a supercooled confinement transition in the early universe. We point out that, when fundamental quanta of the strong sector are swept into exp…
The CLIC Potential for New Physics
J. de Blas, R. Franceschini, F. Riva +100
The Compact Linear Collider (CLIC) is a mature option for the future of high energy physics. It combines the benefits of the clean environment of colliders with operation…
Homeopathic Dark Matter, or how diluted heavy substances produce high energy cosmic rays
Marco Cirelli, Yann Gouttenoire, Kalliopi Petraki +1
We point out that current and planned telescopes have the potential of probing annihilating Dark Matter (DM) with a mass of O(100) TeV and beyond. As a target for such searches, we…
Light Dark Matter at Neutrino Experiments
Yohei Ema, Filippo Sala, Ryosuke Sato
Sub-GeV Dark Matter particles upscattered by cosmic rays gain enough kinetic energy to pass the thresholds of large volume detectors on Earth. We then use public Super-Kamiokande a…
New Axion Searches at Flavor Factories
Xabier Cid Vidal, Alberto Mariotti, Diego Redigolo +2
We assess the impact of searches at flavor factories for new neutral resonances that couple to both photons and gluons. These are well motivated by "heavy axion" solutions of the s…
A light dimuon resonance in B decays?
Filippo Sala
The observed deviations from the Standard Model in several b -> s mu mu processes can be explained in terms of a new vector boson produced on-shell in B meson decays. A mass of 2.5…
Fusing Vectors into Scalars at High Energy Lepton Colliders
Dario Buttazzo, Diego Redigolo, Filippo Sala +1
We study vector boson fusion production of new scalar singlets at high energy lepton colliders. We find that CLIC has the potential to test single production cross-sections of a fe…
Asymmetric dark matter: residual annihilations and self-interactions
Iason Baldes, Marco Cirelli, Paolo Panci +3
Dark matter (DM) coupled to light mediators has been invoked to resolve the putative discrepancies between collisionless cold DM and galactic structure observations. However, -r…
New LHC bound on low-mass diphoton resonances
Alberto Mariotti, Diego Redigolo, Filippo Sala +1
We derive a new bound on diphoton resonances using inclusive diphoton cross section measurements at the LHC, in the so-far poorly constrained mass range between the Upsilon and the…
A New Light Particle in B Decays?
Filippo Sala, David M. Straub
We investigate the possibility whether the tensions with SM expectations observed in several b -> sll transitions, including hints for lepton flavour non-universality, could be due…
R-axion at colliders
Brando Bellazzini, Alberto Mariotti, Diego Redigolo +2
We study the effective theory of a generic class of hidden sectors where supersymmetry is broken together with an approximate R-symmetry at low energy. The light spectrum contains…
Dark Matter's secret liaisons: phenomenology of a dark U(1) sector with bound states
Marco Cirelli, Paolo Panci, Kalliopi Petraki +2
Dark matter (DM) charged under a dark U(1) force appears in many extensions of the Standard Model, and has been invoked to explain anomalies in cosmic-ray data, as well as a self-i…

Epsilon_K in the Standard Model and the kaon phase conventions
Filippo Sala
The parameter epsilon_K, that quantifies CP violation in kaon mixing, is the observable setting the strongest constraints on new physics with a generic flavour and CP structure. Wh…
