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…
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…
Multiple dispersive bounds. I) The z-expansion
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…
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…
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…
