Structure-dependent radiative corrections to $e^{+} e^{-} \to π^{+} π^{-} γ$ in the GVMD approach

Carlo M. Carloni Calame, Marco Ghilardi, Andrea Gurgone +5

We compute the radiative corrections to the process of two-pion production in association with a hard photon in $e^{+} e^{-}$ annihilation by taking into account the non-perturbative s…

Radiative return at NLOPS accuracy

Ettore Budassi, Carlo M. Carloni Calame, Marco Ghilardi +6

The radiative return, together with the energy scan, is the method used at flavour factories to measure the pion form factor, which is a crucial input for the data-driven dispersiv…

Parametrisation and dictionary for CP violating Higgs boson interactions

Daniele Barducci, Matthew Forslund, Marta Fuentes Zamoro +3

Searches for charge-parity (CP) violating interactions of the Standard Model (SM) Higgs boson are a key priority of the LHC physics program. Experimental results from ATLAS and CMS…

Study of the scalar and pseudoscalar meson mass spectrum above the QCD chiral phase transition, using an effective Lagrangian approach

Giulio Cianti, Enrico Meggiolaro

In this work, expanding on previous analyses, we employ an effective Lagrangian approach to investigate the mass spectrum of scalar and pseudoscalar mesons at finite temperature, a…

The $β$ -decay spectrum of Tritiated graphene: combining nuclear quantum mechanics with Density Functional Theory

Andrea Casale, Angelo Esposito, Guido Menichetti +1

We present the results of a multi-methodological study aimed at investigating the interaction between graphene and Tritium during its $β$ -decay to Helium, under different levels of…

Direct Dark Matter searches with Metal Halide Perovskites

Davide Baiocco, Damiano Marian, Giulio Marino +3

Polar materials with optical phonons in the meV range are excellent candidates for both dark matter direct detection (via dark photon-mediated scattering) and light dark matter abs…

Binary superfluids: Low-energy properties and dissipative processes from spontaneous emission of massive phonons

Silvia Trabucco, Luca Lepori, Maria Luisa Chiofalo +1

We discuss the low-energy properties of binary superfluids with density-dependent interactions. Adding an intra-species coupling that induces an explicit soft symmetry-breaking, we…

Is nature natural?

Alessandro Strumia

I summarize the apparent relevance of anthropic selection in understanding unnatural features of the Standard Model, and the consequent implications for theory. This topic, pioneer…

Closing in on new chiral leptons at the LHC

Daniele Barducci, Luca Di Luzio, Marco Nardecchia +1

We study the phenomenological viability of chiral extensions of the Standard Model, with new chiral fermions acquiring their mass through interactions with a single Higgs. We exami…

A Leptonic ALP Portal to the Dark Sector

Giovanni Armando, Paolo Panci, Joachim Weiss +1

We discuss the leptonic ALP portal as a simple scenario that connects observed discrepancies in anomalous magnetic moments to the Dark Matter relic abundance. In this framework an…

Modular invariance and the QCD angle

Ferruccio Feruglio, Alessandro Strumia, Arsenii Titov

String compactifications on an orbi-folded torus with complex structure give rise to chiral fermions, spontaneously broken CP, modular invariance. We show that this allows simple e…

Propagators and widths of physical and purely virtual particles in a finite interval of time

Damiano Anselmi

We study the free and dressed propagators of physical and purely virtual particles in a finite interval of time $τ$ and on a compact space manifold $Ω$ , using coherent states. In t…

Reinterpretation of searches for long-lived particles from meson decays

Rebeca Beltrán, Giovanna Cottin, Martin Hirsch +2

Many models beyond the Standard Model predict light and feebly interacting particles that are often long-lived. These long-lived particles (LLPs) in many cases can be produced from…

Dark matter implications of the neutron anomaly

Leonardo Darini

Motivated by the neutron decay anomaly, we reconsider the neutron decay model $n \to χχχ$ , where the new species $χ$ plays the role of dark matter. We precisely compute the…
