Multi-Higgs Boson Probes of the Dark Sector

Marvin Flores, Christian Gross, Jong Soo Kim +2

We consider dark sectors with spontaneously broken gauge symmetries, where cascade decays of the dark sector fields naturally produce multi-Higgs boson final states along with dark…

Scalar gauge dynamics and Dark Matter

Dario Buttazzo, Luca Di Luzio, Parsa Ghorbani +5

We consider theories with one gauge group (SU, SO or Sp) and one scalar in a two-index representation. The renormalizable action often has accidental symmetries (such as global U(1…

$Δ M_{s}$ theory precision confronts flavour anomalies

Luca Di Luzio, Matthew Kirk, Alexander Lenz +1

Based on recent HQET sum rule and lattice calculations we present updated Standard Model predictions for the mass differences of neutral $B$ mesons: $ΔM_s^{\rm SM} = \left(18.4^{+0…

Covert symmetries in the neutrino mass matrix

Fredrik Björkeroth, Luca Di Luzio, Federico Mescia +1

The flavour neutrino puzzle is often addressed by considering neutrino mass matrices $m$ with a certain number of vanishing entries ( $m_{ij} = 0$ for some values of the indices), sin…

Correlating $ε^{'} / ε$ to hadronic $B$ decays via $U (2)^{3}$ flavour symmetry

Andreas Crivellin, Christian Gross, Stefan Pokorski +1

There are strong similarities between charge-parity (CP) violating observables in hadronic $B$ decays (in particular $Δ A_{CP}^{-}$ in $B \to K π$ ) and direct CP violation in Kaon d…

Directional Dark Matter Detection in Anisotropic Dirac Materials

Ahmet Coskuner, Andrea Mitridate, Andres Olivares +1

Dirac materials, because of their small ${\cal O}(\mbox{meV})$ band gap, are a promising target for dark photon-mediated scattering and absorption of light dark matter. In this pap…

Axion-electron decoupling in nucleophobic axion models

Fredrik Björkeroth, Luca Di Luzio, Federico Mescia +3

The strongest upper bounds on the axion mass come from astrophysical observations like the neutrino burst duration of SN1987A, which depends on the axion couplings to nucleons, or…

Dark Matter from self-dual gauge/Higgs dynamics

Dario Buttazzo, Luca Di Luzio, Giacomo Landini +2

We show that a new gauge group with one new scalar leads to automatically stable Dark Matter candidates. We consider theories where the Higgs phase is dual to the confined phase: i…

Study of the interactions of the axion with mesons and photons using a chiral effective Lagrangian model

Giacomo Landini, Enrico Meggiolaro

We investigate the most interesting decay processes involving axions, photons and the lightest pseudoscalar mesons, making use of a chiral effective Lagrangian model with $L = 3$ lig…

Simplified Template Cross Sections -- Stage 1.1 and 1.2

Nicolas Berger, Claudia Bertella, Matteo Bonanomi +25

Simplified Template Cross Sections (STXS) have been adopted by the LHC experiments as a common framework for Higgs measurements. Their purpose is to reduce the theoretical uncertai…

Can the ANITA anomalous events be due to new physics?

James M. Cline, Christian Gross, Wei Xue

The ANITA collaboration has observed two ultra-high-energy upgoing air shower events that cannot originate from Standard Model neutrinos that have traversed the Earth. Several beyo…

Quark masses, CKM angles and Lepton Flavour Universality violation

Riccardo Barbieri, Robert Ziegler

A properly defined and suitably broken $U (2)$ flavour symmetry leads to successful quantitative relations between quark mass ratios and CKM angles. At the same time the intrinsic d…

Theta dependence of the vacuum energy density in chiral effective Lagrangian models at finite temperature, above $T_{c}$

Enrico Meggiolaro

In this work, extending a previous study at zero temperature ( $T = 0$ ), we perform a systematic study of the modifications to the QCD vacuum energy density $ε_{v a c}$ in the finite-te…

Coset Cosmology

Luca Di Luzio, Michele Redi, Alessandro Strumia +1

We show that the potential of Nambu-Goldstone bosons can have two or more local minima e.g. at antipodal positions in the vacuum manifold. This happens in many models of composite…
