Higgs-Pair Production via Gluon Fusion: Top-Yukawa- and light-quark-induced electroweak Corrections
Arunima Bhattacharya, Francisco Campanario, Sauro Carlotti +5
Gluon fusion, , is the dominant Higgs-pair production process at the Large Hadron Collider (LHC) and provides the first direct access to the trilinear Higgs self-interact…
Higgs pair production in gluon fusion to higher orders in Higgs Effective Field Theory
Ilaria Brivio, Ramona Gröber, Konstantin Schmid
Higgs pair production offers the opportunity to probe correlations among the couplings of one or two Higgs bosons to fermions and gauge bosons. In this context, it serves as a powe…
The Art of Counting: a reappraisal of the HEFT expansion
Ilaria Brivio, Ramona Gröber, Konstantin Schmid
We revisit the power counting of the Higgs Effective Field Theory (HEFT) from first principles, by requiring that predictions for physical observables follow a series expansion in…
Viability of , and Flavour Symmetries in Light of the First JUNO Result
S. T. Petcov, A. V. Titov
We update the analysis of the viability of the lepton mixing patterns originating from , and discrete flavour symmetries and leading to predictions for the solar n…
Stripped-Envelope Supernovae for QCD Axion Detection
Francisco R. Candón, Damiano F. G. Fiorillo, Ángel Gil Muyor +3
QCD axions would be copiously produced in the proto-neutron star formed in a core-collapse supernova (SN). After escaping, they would convert into gamma rays in the Galactic magnet…
Ultralight Dark Matter from the Edge of Field Space
Mathias Becker, Francesco D'Eramo, Ville Vaskonen
We introduce a novel class of bosonic dark matter candidates that we dub wallions, featuring boundaries in field space. The wallion mass is exponentially suppressed when the separa…
Seasons of Dark Matter Freeze-In Shaped by the Weather of the Early Universe
Francesco D'Eramo, Alessandro Lenoci, Tommaso Sassi
Quantifying the imprints of freeze-in dark matter (DM) on cosmological structures requires knowledge of its phase-space distribution. We investigate how variations in the cosmologi…
Complete two-loop Yukawa-induced running of the Higgs-gluon coupling in SMEFT
Stefano Di Noi, Barbara Anna Erdelyi, Ramona Gröber
We compute the two-loop renormalisation group equation for the effective Higgs to gluon coupling in Standard Model Effective Field Theory. Concretely, we present the contributions…
Positivity and partial wave unitarity bounds on ALP theories via amplitude methods
Luigi C. Bresciani, Gabriele Levati, Paride Paradisi
We derive the complete set of partial wave unitarity bounds on the most general Axion-Like Particle (ALP) effective interactions up to dimension 8 in the limit of large center-of-m…
Small Progenitors, Large Couplings: Type Ic Supernova Constraints on Radiatively Decaying Particles
Francisco R. Candón, Damiano F. G. Fiorillo, Hans-Thomas Janka +2
Supernova (SN) 1987A provides classic bounds on gamma-ray flashes from the radiative decay of sub-GeV particles, but the latter may decay so rapidly as to be shielded by the stella…
Axion-photon conversion in transient compact stars: Systematics, constraints, and opportunities
Damiano F. G. Fiorillo, Ángel Gil Muyor, Hans-Thomas Janka +2
We study magnetic conversion of ultra-relativistic axion-like particles (ALPs) into photons in compact-star environments, focusing on the hot, transient conditions of core-collapse…
Probing a Light Scalar Boson with a few-MeV Proton Beam Deep Underground
Carlo Broggini, Giuseppe Di Carlo, Luca Di Luzio +2
We propose to investigate the production of a light scalar boson in low-energy proton-nucleus interactions using the 3.5 MV accelerator of the Bellotti Ion Beam Facility, locat…
Multi-Higgs Amplitudes Bootstrapped: Dissecting SMEFT and HEFT
Ramona Gröber, Alejo N. Rossia, Michał Ryczkowski
The precise measurement of the Higgs boson properties requires a robust framework to parametrize possible deviations from Standard Model (SM) predictions in the most model-independ…

Benjamin Campillo Aveleira, Long Chen, Joshua Davies +9
We present state-of-the-art predictions for the inclusive cross section of gluon-initiated production, following the recommendations of the LHC Higgs Working Group. In particu…
Probing Non-Minimal Dark Sectors via the 21 cm Line at Cosmic Dawn
Federico Cima, Francesco D'Eramo
Observations of the hydrogen hyperfine transition through the 21 cm line near the end of the cosmic dark ages provide unique opportunities to probe new physics. In this work, we in…
Two loops, four tops and two schemes: a renormalization story
Stefano Di Noi, Ramona Gröber
We calculate the four-top quark operator contributions to the two-loop renormalization constants of the fermion and gluon fields, necessary to obtain the renormalization group equa…
Leading bounds on micro- to picometer fifth forces from neutron star cooling
Damiano F. G. Fiorillo, Alessandro Lella, Ciaran A. J. O'Hare +1
The equivalence principle and the inverse-square law of gravity could be violated at short distances ( to meters) by scalars sporting a coupling to nucleo…
Dark Matter Freeze-In and Small-Scale Observables: Novel Mass Bounds and Viable Particle Candidates
Francesco D'Eramo, Alessandro Lenoci, Ariane Dekker
The suppression of cosmological structure at small scales is a key signature of dark matter (DM) produced via freeze-in in the low-mass regime. We present a comprehensive analysis…
Hunting for a 17 MeV particle coupled to electrons
Luca Di Luzio, Paride Paradisi, Nudzeim Selimovic
We discuss a set of precision observables that can probe the existence of a light particle coupled to electrons in the mass range of 1-100 MeV. As a case study, we consider the…
Amplitudes and partial wave unitarity bounds
Luigi C. Bresciani, Gabriele Levati, Paride Paradisi
We develop a formalism, based on spinor-helicity techniques, to generalize the formulation of partial wave unitarity bounds. We discuss unitarity bounds for (with $N,M \g…
