Minimal spontaneous baryogenesis from flavor
Martin A. Mojahed, Alfredo Stanzione
In its minimal realization, the Froggatt-Nielsen (FN) mechanism addresses the Standard Model (SM) flavor puzzle via the spontaneous breaking of a horizontal symmetry. If $…
Axion-driven spontaneous leptogenesis, precisely
Konstantin Kuckenberg, Martin A. Mojahed, Kai Schmitz +1
We revisit a minimal scenario for spontaneous leptogenesis where the asymmetry generation is driven by a heavy axion-like field evolving via standard misalignment. We focus on the…
Freeze-in leptogenesis without the need for right-handed neutrino oscillations
Martin A. Mojahed, Sascha Weber
We present an experimentally testable leptogenesis mechanism based on the standard type-I seesaw model that successfully operates at right-handed-neutrino (RHN) masses around the G…
Asymgenesis
Martin A. Mojahed, Sascha Weber
We present a framework based on the standard type-I seesaw model that relates the baryon asymmetry of the universe to the dark matter (DM) density. The framework, which we name "As…
A lower bound on the right-handed neutrino mass from wash-in leptogenesis
Martin A. Mojahed, Kai Schmitz, Dominik Wilken
Leptogenesis is an attractive scenario for the generation of the baryon asymmetry of the Universe that relies on the dynamics of right-handed neutrinos (RHNs) in the seesaw extensi…
Gravitational charge production
Martin A. Mojahed, Kai Schmitz, Xun-Jie Xu
Wash-in leptogenesis is an attractive mechanism to produce the baryon asymmetry of the Universe. It treats right-handed-neutrino interactions as spectator processes, on the same fo…
Graviton- and Inflaton-mediated Dark Matter Production after Large Field Polynomial Inflation
Nicolás Bernal, Julia Harz, Martin A. Mojahed +1
Polynomial inflation is a simple cosmological scenario, which fits the cosmic microwave background data well. It provides testable predictions for the tensor-to-scalar ratio and th…
Disentangling new physics in and observables
Andrzej J. Buras, Julia Harz, Martin A. Mojahed
We investigate the possibility of disentangling different new physics contributions to the rare meson decays and $B\rightarrow K(K^*)+\displays…
Quark, pion and axial condensates in three-flavor finite isospin chiral perturbation theory
Prabal Adhikari, Jens O. Andersen, Martin A. Mojahed
We calculate the light quark condensate, the strange quark condensate, the pion condensate, and the axial condensate in three-flavor chiral perturbation theory (PT) in the prese…
Condensates and pressure of two-flavor chiral perturbation theory at nonzero isospin and temperature
Prabal Adhikari, Jens O. Andersen, Martin A. Mojahed
We consider two-flavor chiral perturbation theory (PT) at finite isospin chemical potential and finite temperature . We calculate the effective potential and the quark…
