Insights on the Cosmic Origin of Matter from Proton Stability
Admir Greljo, Xavier Ponce Díaz, Anders Eller Thomsen
We investigate the phenomenology of a model in which the proton is rendered absolutely stable by an IR mechanism that remains robust against unknown quantum gravity effects. A line…
Recent Progress in Flavor Model Building
Wolfgang Altmannshofer, Admir Greljo
The flavor puzzles remain among the most compelling open questions in particle physics. The striking hierarchies observed in the masses and mixing of charged fermions define the St…
Discovering heavy neutrino-antineutrino oscillations at the -pole
Stefan Antusch, Jan Hajer, Bruno M. S. Oliveira
Collider-testable type I seesaw extensions of the Standard Model are generally protected by an approximate lepton number (LN) symmetry. Consequently, they predict pseudo-Dirac heav…
Cosmic Strings from Tribrid Inflation
Stefan Antusch, Katarina Trailović
Tribrid inflation is a class of supersymmetric inflation models where the scalar component of a matter superfield, or a -flat direction of matter fields, drives inflation. Simil…
Center-of-mass recoil effects on the annihilation and formation of dark matter bound pairs
Simone Biondini, Nora Brambilla, Gramos Qerimi +1
For a quantitative investigation on the time evolution of heavy thermal dark matter at and after thermal freeze-out, near-threshold processes need to be taken into account which ha…
Functional Matching and Renormalization Group Equations at Two-Loop Order
Javier Fuentes-Martín, Ajdin Palavrić, Anders Eller Thomsen
We present a systematic method for determining the two-loop effective Lagrangian resulting from integrating out a set of heavy particles in an ultraviolet scalar theory. We prove t…
Light Neutrinophilic Dark Matter from a Scotogenic Model
Johannes Herms, Sudip Jana, Vishnu P. K. +1
We present a minimal sub-GeV thermal Dark Matter (DM) model where the DM primarily interacts with neutrinos and participates in neutrino mass generation through quantum loop correc…
Computing Tools for Effective Field Theories
Jason Aebischer, Matteo Fael, Javier Fuentes-Martín +30
In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In…
Primordial non-Gaussianity as a probe of seesaw and leptogenesis
Chee Sheng Fong, Anish Ghoshal, Abhishek Naskar +2
We present the possibility that the seesaw mechanism and nonthermal leptogenesis can be {investigated} via primordial non-Gaussianities in the context of a majoron curvaton model.…
Non-perturbative effects for dark sectors with QCD portals
Simone Biondini, Talal Ahmed Chowdhury, Shaikh Saad
In this work, we consider a class of dark matter (DM) models where the DM does not directly interact with the Standard Model (SM) particles at the tree-level. Therefore, the coanni…
Cross section for supernova axion observation in neutrino water Cherenkov detectors
Pierluca Carenza, Giampaolo Co', Maurizio Giannotti +4
Axions coupled to nucleons might be copiously emitted from core-collapse supernovae (SNe). If the axion-nucleon coupling is strong enough, axions would be emitted from the SN as a…
Getting the most on supernova axions
Alessandro Lella, Pierluca Carenza, Giampaolo Co' +4
Axion-like particles (ALPs) coupled to nucleons might be copiously emitted from a supernova (SN) core. We extend existing bounds on free-streaming ALPs to the case in which these a…
Effective Field Theories for Dark Matter Pairs in the Early Universe
Simone Biondini, Nora Brambilla, Gramos Qerimi +1
In this conference paper, we consider effective field theories of non-relativistic dark matter particles interacting with a light force mediator in the early expanding universe. We…
Quark-lepton Yukawa ratios and nucleon decay in SU(5) GUTs with type-III seesaw
Stefan Antusch, Kevin Hinze, Shaikh Saad
We consider an extension of the Georgi-Glashow SU(5) GUT model by a 45-dimensional scalar and a 24-dimensional fermionic representation, where the latter leads to the generation of…
Fully Testable Axion Dark Matter within a Minimal GUT
Stefan Antusch, Ilja Doršner, Kevin Hinze +1
We present a minimal Grand Unified Theory model, based on gauge symmetry and a global Peccei-Quinn symmetry, that predicts the existence of an ultralight axion dark…
Rare decays meet high-mass Drell-Yan
Admir Greljo, Jakub Salko, Aleks Smolkovič +1
Rare hadron decays are considered excellent probes of new semileptonic four-fermion interactions of microscopic origin. However, the same interactions also correct the high-mas…
Probing Minimal Grand Unification through Gravitational Waves, Proton Decay, and Fermion Masses
Shaikh Saad
Motivated by the direct discovery of gravitational waves (GWs) from black holes and neutron stars, there is a growing interest in investigating GWs from other sources. Among them,…
Beyond lepton number violation at the HL-LHC: Resolving heavy neutrino-antineutrino oscillations
Stefan Antusch, Jan Hajer, Johannes Rosskopp
Collider testable low-scale seesaw models predict pseudo-Dirac heavy neutrinos, that can produce an oscillating pattern of lepton number conserving and lepton number violating even…

S. Hasibul Hassan Chowdhury, Talal Ahmed Chowdhury, Salah Nasri +2
Quantum simulation has become a promising avenue of research that allows one to simulate and gain insight into the models of High Energy Physics whose experimental realizations are…
Asymmetric Leptoquark Pair Production at LHC
Ilja Doršner, Ajla Lejlić, Shaikh Saad
We investigate asymmetric leptoquark pair production mechanism at the Large Hadron Collider to advocate its potential relevance to establish reliable constraints on the leptoquark…
Simulating lepton number violation induced by heavy neutrino-antineutrino oscillations at colliders
Stefan Antusch, Jan Hajer, Johannes Rosskopp
We study pseudo-Dirac pairs of two almost mass-degenerate sterile Majorana neutrinos which generate light neutrino masses via a low-scale seesaw mechanism. These pseudo-Dirac heavy…

Simone Biondini, Philipp Schicho, Tuomas V. I. Tenkanen
Beyond the Standard Model physics is required to explain both dark matter and the baryon asymmetry of the universe, the latter possibly generated during a strong first-order electr…
