Refining two-loop corrections to trilinear Higgs couplings in the Two-Higgs-Doublet Model
Johannes Braathen, Felix Egle, Alain Verduras Schaeidt
The precise determination of the Higgs self-couplings is an essential task for understanding electroweak symmetry breaking and probing physics beyond the Standard Model (SM). The c…
Investigating a strong first-order electroweak phase transition in the RxSM at future linear colliders and LISA
Johannes Braathen, Sven Heinemeyer, Carlos Pulido Boatella +1
The general real singlet extension of the Standard Model (SM), the RxSM, is one of the simplest theories Beyond-the-Standard Model (BSM) that can accommodate a strong first-order e…
On the Robustness of type-II Seesaw Collider Searches
Christoph Englert, Manimala Mitra, Wrishik Naskar +1
Electroweak triplet Higgs sector extensions are well-motivated scenarios to address lepton flavour observations. These models can also be strongly constrained by combining precise,…
Single-wave solutions of the neutrino fast flavor system. Part II. Weak instabilities and their resonant behavior
Damiano F. G. Fiorillo, Georg G. Raffelt
Flavor instabilities in dense neutrino media trigger exponential growth of flavor waves, yet their nonlinear saturation remains poorly understood. We examine a simple proxy for thi…
Single-wave solutions of the neutrino fast flavor system. Part I. Mechanical properties
Damiano F. G. Fiorillo, Georg G. Raffelt
A dense neutrino plasma can exhibit collective flavor evolution caused by neutrino--neutrino refraction. Recently, a new class of exact nonlinear inhomogeneous solutions was discov…
Very-High-Frequency Gravitational Waves from Multi-Monodromy Inflation
Guido D'Amico, Andrew A. Geraci, Nemanja Kaloper +1
We show that in multi-stage axion monodromy inflation an interruption near the end of the penultimate stage can lead to a spike in the gravitational wave background. These gravitat…
Fermion (non)reheating with a quartic inflaton potential
Nabeen Bhusal, Ernesto Chávez M., Marcos A. G. Garcia +2
Any viable inflationary model must account for reheating of the universe prior to the onset of primordial nucleosynthesis. In this work, we study the (p)reheating mechanism for an…
Stellar Superradiance and Low-Energy Absorption in Dense Nuclear Media
Zhaoyu Bai, Vitor Cardoso, Yifan Chen +3
Ultralight bosons such as axions and dark photons are well-motivated hypothetical particles, whose couplings to ordinary matter can be effectively constrained by stellar cooling. L…
Could electron-top interactions spoil the measurement of the Higgs trilinear? -A quantitative estimate at future lepton colliders-
Lukas Allwicher, Christophe Grojean, Lucine Tabatt
The measurement of the Higgs self-coupling is considered the next milestone in the study of the Higgs boson properties. At future facilities below the double Higgs product…
Assessing (H)EFT theory errors by pitting EoM against Field Redefinitions
Rodrigo Alonso, Christoph Englert, Wrishik Naskar +1
Truncations of effective field theory expansions are technically necessary but inherently intertwined with the redundancies of general field redefinitions. This can be viewed as a…
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…
Primer of Strong-Field Quantum Electrodynamics for Experimentalists
Annabel Kropf, Ivo Schulthess
This document serves as a conceptual and practical introduction to Strong-Field Quantum Electrodynamics (SFQED), written from the standpoint of experimental physicists. Rather than…
Interpretation of LHC excesses at 95 GeV and 152 GeV in an extended Georgi-Machacek model
Ting-Kuo Chen, Cheng-Wei Chiang, Sven Heinemeyer +1
We analyze the excesses at 95 GeV in the light Higgs-boson searches in the di-photon decay channel reported by CMS and ATLAS, which combined are at the level of three standard devi…
Gravitational waves from the sound shell model: direct and inverse phase transitions in the early Universe
Giulio Barni, Simone Blasi, Eric Madge +1
Cosmological phase transitions are a frequent phenomenon in particle physics models beyond the Standard Model, and the corresponding gravitational wave signal offers a key probe of…
Modelling production for the LHC at 13.6 TeV
Christian Biello, Alessandro Gavardi, Rebecca von Kuk +10
We present new state-of-the-art predictions for Standard Model Higgs boson production in association with a bottom-quark pair (). Updated cross sections are computed in a…
Probing Quadratically Coupled Ultralight Dark Matter with Pulsar Timing Arrays
Xucheng Gan, Hyungjin Kim, Andrea Mitridate
Ultralight dark matter may couple quadratically to Standard Model particles. Such quadratic interactions give rise to both coherent and stochastic signals in pulsar timing array (P…
Complementarity of gravitational wave analyses and di-Higgs production in the exploration of the Electroweak Phase Transition dynamics in the RxSM
Johannes Braathen, Sven Heinemeyer, Carlos Pulido Boatella +1
The real singlet extension of the Standard Model (SM), RxSM, is one of the simplest Beyond-the-Standard Model (BSM) theories that can accommodate a strong first-order electroweak p…
A SHIFT of Perspective: Observing Neutrinos at CMS and ATLAS
Alfonso Garcia-Soto, Jeremi Niedziela
The SHIFT@LHC proposal introduced a novel shifted gaseous fixed-target concept at the LHC to search for exotic particles. In this letter, we explore an entirely different physics o…
Monte Carlo Event Generators
Jürgen Reuter
Monte Carlo event generators are in a modern terminology the digital twins of collider-based particle physics experiment. We give an introduction into the application of MC generat…
Configuration and Benchmarking of Processes with K4GeneratorsConfig
Alan Price, Dirk Zerwas
The next generation of electron-positron colliders will require unprecedented precision in both theory and experiment. Sophisticated software frameworks are essential to evaluate d…
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…
