Proton decay into charged leptons
Thomas Hambye, Julian Heeck
We discuss proton and neutron decays involving three leptons in the final state. Some of these modes could constitute the dominant decay channel because they conserve lepton-flavor…
Lepton Flavor Violation with Displaced Vertices
Julian Heeck, Werner Rodejohann
If light new physics with lepton-flavor-violating couplings exists, the prime discovery channel might not be but rather , where the new boson co…
On Minimal Dark Matter coupled to the Higgs
Laura Lopez-Honorez, Michel H. G. Tytgat, Pantelis Tziveloglou +1
We provide a unified presentation of extensions of the Minimal Dark Matter framework in which new fermionic electroweak multiplets are coupled to each other via the Standard Model…
Probing Leptogenesis
E. J. Chun, G. Cvetič, P. S. B. Dev +12
The focus of this chapter lies on the possible experimental tests of leptogenesis scenarios. We consider both leptogenesis generated from oscillations, as well as leptogenesis from…
ARS Leptogenesis
M. Drewes, B. Garbrecht, P. Hernandez +6
We review the current status of the leptogenesis scenario originally proposed by Akhmedov, Rubakov and Smirnov (ARS). It takes place in the parametric regime where the right-handed…
Leptogenesis Constraints on breaking Higgs Boson in TeV Scale Seesaw Models
P. S. Bhupal Dev, Rabindra N. Mohapatra, Yongchao Zhang
In the type-I seesaw mechanism for neutrino masses, there exists a symmetry, whose breaking leads to the lepton number violating mass of the heavy Majorana neutrinos. This wo…
Resonant enhancement in leptogenesis
P. S. Bhupal Dev, Mathias Garny, Juraj Klaric +2
Vanilla leptogenesis within the type I seesaw framework requires the mass scale of the right-handed neutrinos to be above 10^9 GeV. This lower bound can be avoided if at least two…
Flavor effects in leptogenesis
P. S. Bhupal Dev, Pasquale Di Bari, Bjorn Garbrecht +3
Flavor effects can have a significant impact on the final estimate of the lepton (and therefore baryon) asymmetry in scenarios of leptogenesis. It is therefore necessary to account…
Cold light dark matter in extended seesaw models
Sami Boulebnane, Julian Heeck, Anne Nguyen +1
We present a thorough discussion of light dark matter produced via freeze-in in two-body decays A -> B DM. If A and B are quasi-degenerate, the dark matter particle has a cold spec…
Self-interacting Spin-2 Dark Matter
Xiaoyong Chu, Camilo Garcia-Cely
Recent developments in bigravity allow one to construct consistent theories of interacting spin-2 particles that are free of ghosts. In this framework, we propose an elementary spi…
Cold keV dark matter from decays and scatterings
Julian Heeck, Daniele Teresi
We explore ways of creating cold keV-scale dark matter by means of decays and scatterings. The main observation is that certain thermal freeze-in processes can lead to a cold dark…
Double non-perturbative gluon exchange: an update on the soft Pomeron contribution to pp scattering
F. E. Canfora, D. Dudal, I. F. Justo +4
We employ a set of recent, theoretically motivated, fits to non-perturbative unquenched gluon propagators to check in how far double gluon exchange can be used to describe the soft…
The Inflaton Portal to Dark Matter
Lucien Heurtier
We consider the possibility that the inflaton is part of the dark sector and interacts with the standard model through a portal interaction with a heavy complex scalar field in equ…
CP violation effects in the diphoton spectrum of heavy scalars
Ligong Bian, Ning Chen, Yongchao Zhang
In a class of new physics models, an extended Higgs sector and new CP-violating sources are simultaneously present in order to explain the baryon asymmetry in the Universe. The aim…
Towards a medium-scale axion helioscope and haloscope
V. Anastassopoulos, F. Avignone, A. Bykov +32
We discuss the physics case for and the concept of a medium-scale axion helioscope with sensitivities in the axion-photon coupling a few times better than CERN Axion Solar Telescop…
Prospects for discovering a neutrino line induced by dark matter annihilation
Chaimae El Aisati, Camilo Garcia-Cely, Thomas Hambye +1
In the near future, neutrino telescopes are expected to improve their sensitivity to the flux of monochromatic neutrinos produced by dark matter (DM) in our galaxy. This is illustr…
Baryogenesis from L-violating Higgs-doublet decay in the density-matrix formalism
Thomas Hambye, Daniele Teresi
We compute in the density-matrix formalism the baryon asymmetry generated by the decay of the Higgs doublet into a right-handed (RH) neutrino and a Standard Model lepton. The empha…
Exact RG Invariance and Symmetry Improved 2PI Effective Potential
Apostolos Pilaftsis, Daniele Teresi
The Symmetry Improved Two-Particle-Irreducible (SI2PI) formalism is a powerful tool to calculate the effective potential beyond perturbation theory, whereby infinite sets of select…
Long Lived Light Scalars as Probe of Low Scale Seesaw Models
P. S. Bhupal Dev, Rabindra N. Mohapatra, Yongchao Zhang
We point out that in generic TeV scale seesaw models for neutrino masses with local symmetry breaking, there is a phenomenologically allowed range of parameters where the Hig…
Neutrino Lines from Majoron Dark Matter
Camilo Garcia-Cely, Julian Heeck
Models with spontaneously broken global lepton number can lead to a pseudo-Goldstone boson as a long-lived dark matter candidate. Here we revisit the case of singlet majoron dark m…
