Magnetic-monopole resummation justifies perturbatively calculated collider production cross sections
Jean Alexandre, Nick E. Mavromatos, Vasiliki A. Mitsou +1
A one-loop resummation scheme, inspired by Dyson-Schwinger (DS) formalism of strongly coupled quantum field theories, is applied to spin-1/2 magnetic monopoles (MMs), in the contex…
Compact Stars as Portals to Extra-Dimensional Dark Matter
Raghuveer Garani, Chris Kouvaris, Michel H. G. Tytgat +1
We investigate hydrostatic configurations of asymmetric dark matter (DM) spheres in scenarios where fermionic DM can propagate into extra spatial dimensions, while Standard Model f…
Axion-mediated photon-to-photon transitions in high finesse dielectric resonators
Evangelos Almpanis
Axions are hypothetical particles that could address both the strong charge-parity problem in quantum chromodynamics and the enigmatic nature of dark matter. However, if axions exi…
Energy-scaling behavior of intrinsic transverse momentum parameters in Drell-Yan simulation
CMS Collaboration
An analysis is presented based on models of the intrinsic transverse momentum (intrinsic ) of partons in nucleons by studying the dilepton transverse momentum in Drel…
Flavour in Finite Grand Unified Models
Luis Odín Estrada Ramos, Myriam Mondragón, Gregory Patellis +1
Four supersymmetric models which exhibit and/or symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The fi…
Searching for Minicharged Particles at the Energy Frontier with the MoEDAL-MAPP Experiment at the LHC
Vasiliki A. Mitsou, Marc de Montigny, Abhinab Mukhopadhyay +4
MoEDAL's Apparatus for Penetrating Particles (MAPP) Experiment is designed to expand the search for new physics at the LHC, significantly extending the physics program of the basel…
Resummation schemes for high-electric-charge objects leading to improved experimental mass limits
Jean Alexandre, Nick E. Mavromatos, Vasiliki A. Mitsou +1
High-Electric-Charge compact Objects (HECOs) appear in several theoretical particle physics models beyond the Standard Model, and are actively searched for in current colliders, su…
Defrosting and Blast Freezing Dark Matter
Marcos M. Flores, Chris Kouvaris, Alexander Kusenko
We show that the present-day dark matter abundance can be produced through a novel mechanism that involves a very rapid thermal freeze-out caused by inhomogeneous heating and succe…
Proton capture in compact dark stars and observable implications
Boris Betancourt Kamenetskaia, Anja Brenner, Alejandro Ibarra +1
Asymmetric dark matter under certain conditions could form compact star-like objects, which can be searched either through gravitational lensing or by observation of gravitational…
Schwinger-Dyson equations and mass generation for an axion theory with a PT symmetric Yukawa fermion interaction
N. E. Mavromatos, Sarben Sarkar, A. Soto
A nonperturbative Schwinger-Dyson analysis of mass generation is presented for a non-Hermitian PT-symmetric field theory in four dimensions of an axion coupled to a Dirac fermion.T…
On the Cosmological Stability of the Higgs Instability
Valerio De Luca, Alex Kehagias, Antonio Riotto
The Standard Model Higgs potential becomes unstable at large Higgs field values where its quartic coupling becomes negative. While the tunneling lifetime of our current electroweak…
Light-by-Light Scattering at Future Colliders
John Ellis, Nick E. Mavromatos, Philipp Roloff +1
We study the sensitivity of possible CLIC and FCC-ee measurements of light-by-light scattering to old and new physics, including the Heisenberg-Euler Lagrangian in the Standard Mod…
Two-loop non-planar hexa-box integrals with one massive leg
Adam Kardos, Costas G. Papadopoulos, Alexander V. Smirnov +2
Based on the Simplified Differential Equations approach, we present results for the two-loop non-planar hexa-box families of master integrals. We introduce a new approach to obtain…
Quantum gravity phenomenology at the dawn of the multi-messenger era -- A review
A. Addazi, J. Alvarez-Muniz, R. Alves Batista +157
The exploration of the universe has recently entered a new era thanks to the multi-messenger paradigm, characterized by a continuous increase in the quantity and quality of experim…
A comment on lepton mixing
Dimitrios Metaxas
Since right-handed neutrinos, if added to the Standard Model, have no gauge interactions, their kinetic terms can be mixed. I examine the related rotations of the gauge eigenstates…
Using atomic clocks to detect local dark matter halos
Chris Kouvaris, Eleftherios Papantonopoulos, Lauren Street +1
It is possible that bosonic dark matter forms halos around the Sun or the Earth. We discuss the possibility of probing such halos with atomic clocks. Focusing on either a Higgs por…
Pentagon integrals to arbitrary order in the dimensional regulator
Nikolaos Syrrakos
We analytically calculate one-loop five-point Master Integrals, \textit{pentagon integrals}, with up to one off-shell leg to arbitrary order in the dimensional regulator in $d=4-2ε…
Probing Unified Theories with Reduced Couplings at Future Hadron Colliders
Sven Heinemeyer, Jan Kalinowski, Wojciech Kotlarski +4
The search for renormalization group invariant relations among parameters to all orders in perturbation theory constitutes the basis of the reduction of couplings concept. Reductio…
Gauge independence of the physical fermion mass in the effective action of theories with radiative symmetry breaking
Dimitrios Metaxas
I consider an Abelian gauge theory, with a complex scalar field and massless, chiral fermions, in the limit where the couplings and the interactions induce radiative symmetry break…

Dhimiter D. Canko, Nikolaos Syrrakos
We present in detail two resummation methods emerging from the application of the Simplified Differential Equations approach to a canonical basis of master integrals. The first one…
