Chiral models of composite axions and accidental Peccei-Quinn symmetry

Roberto Contino, Alessandro Podo, Filippo Revello

We introduce a class of composite axion models that provide a natural solution to the strong CP problem, and possibly account for the observed dark matter abundance. The QCD axion…

Dark Matter abundance via thermal decays and leptoquark mediators

Benedetta Belfatto, Dario Buttazzo, Christian Gross +5

We explore a new mechanism for reproducing the Dark Matter (DM) abundance: scatterings of one DM particle on light Standard Model particles. Strong bounds on its decays can be sati…

Non-resonant new physics search at the LHC for the $b \to c τ ν$ anomalies

Motoi Endo, Syuhei Iguro, Teppei Kitahara +2

Motivated by the $b \to c τ ν$ anomalies, we study non-resonant searches for new physics at the large hadron collider (LHC) by considering final states with an energetic an…

Unveiling Hidden Physics at the LHC

Oliver Fischer, Bruce Mellado, Stefan Antusch +30

The field of particle physics is at the crossroads. The discovery of a Higgs-like boson completed the Standard Model (SM), but the lacking observation of convincing resonances Beyo…

Exclusive determinations of $∣ V_{c b} ∣$ and $R (D^{*})$ through unitarity

G. Martinelli, S. Simula, L. Vittorio

In this work we apply the Dispersive Matrix (DM) method of Refs. [1,2] to the lattice computations of the Form Factors (FFs) entering the semileptonic $B \to D^{*} ℓ ν_{ℓ}$ decay…

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…

$τ \to ℓ +$ invisible through invisible-savvy collider variables

Diego Guadagnoli, Chan Beom Park, Francesco Tenchini

New particles $ϕ$ in the MeV-GeV range produced at colliders and escaping detection can be searched for at operating $b -$ and $τ -$ factories such as Belle II. A typical search topol…

$∣ V_{c b} ∣$ and $R (D^{(*)})$ using lattice QCD and unitarity

G. Martinelli, S. Simula, L. Vittorio

The Cabibbo-Kobayashi-Maskawa (CKM) matrix element $∣ V_{c b} ∣$ is extracted from exclusive semileptonic $B \to D^{(*)}$ decays adopting a novel unitarity-based approach which allows…

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…

Vacuum Stability vs. Positivity in Real Singlet Scalar Extension of the Standard Model

Parsa Ghorbani

We assume a generic real singlet scalar extension of the Standard Model living in the vacuum $(v, w)$ at the electroweak scale with $v = 246$ GeV and $w$ being respectively the Higgs…

A fake doublet solution to the muon anomalous magnetic moment

Damiano Anselmi, Kristjan Kannike, Carlo Marzo +5

Extensions to the Standard Model that use strictly off-shell degrees of freedom - the fakeons - allow for new measurable interactions at energy scales usually precluded by the cons…

Phenomenology of a Fake Inert Doublet Model

Damiano Anselmi, Kristjan Kannike, Carlo Marzo +5

We introduce a new way of modeling the physics beyond the Standard Model by considering fake, strictly off-shell degrees of freedom: the fakeons. To demonstrate the approach and ex…

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…

Are the CKM anomalies induced by vector-like quarks? Limits from flavor changing and Standard Model precision tests

Benedetta Belfatto, Zurab Berezhiani

Recent high precision determinations of $V_{u s}$ and $V_{u d}$ indicate towards anomalies in the first row of the CKM matrix. Namely, determination of $V_{u d}$ from superallowed bet…

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…
