A Dispersive Look at Rare -meson Semileptonic Decays
Marco Ciuchini, Marco Fedele, Ayan Paul +5
Rare semileptonic flavour-changing neutral current transitions provide stringent tests of the Standard Model. Their interpretation is limited by hadronic uncertainties, n…
Constraints on a Light Leptophilic Scalar from Dark-Sector Couplings
Marco Graziani, Giacomo Landini, Federico Mescia +2
We study a minimal framework where a Majorana fermion dark matter particle interacts with a light scalar mediator coupled mainly to electrons. We examine both freeze-out and freeze…
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…
Multiple dispersive bounds. II) Sub-threshold branch-cuts
Silvano Simula, Ludovico Vittorio
We apply the strategy proposed in the companion paper [1] for dealing with multiple dispersive bounds, to the case of sub-threshold branch-cuts, which is a topic addressed extensiv…

Silvano Simula, Ludovico Vittorio
We propose the implementation of two ingredients in the phenomenological applications of the unitary approach based on the -expansion of hadronic form factors, commonly referred…

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…
Probing the general axion-nucleon interaction in water Cherenkov experiments
Mael Cavan-Piton, Diego Guadagnoli, Axel Iohner +2
We consider an axion flux on Earth consistent with emission from the Supernova explosion SN 1987A. Using Chiral Perturbation Theory augmented with an axion, we calculate the energy…
Probing QCD Axions or Axion-like Particles in three-body Decays

Two-body decays like rank among the most constraining collider probes for new, low-mass, feebly interacting pseudoscalar particles . We explore an alternative class o…
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…

We present updated estimates of and based on all the available theoretical and experimental data on semileptonic decay…
Axion emission from strange matter in core-collapse SNe
Mael Cavan-Piton, Diego Guadagnoli, Micaela Oertel +2
The duration of the neutrino burst from the supernova event SN 1987A is known to be sensitive to exotic sources of cooling, such as axions radiated from the dense and hot hadronic…
