Hypermagnetogenesis from axion inflation: Model-independent estimates

E. V. Gorbar, K. Schmitz, O. O. Sobol +1

Axion inflation coupled to the Standard Model (SM) hypercharge gauge sector represents an attractive scenario for the generation of primordial hypermagnetic fields. The description…

Leptoflavorgenesis: baryon asymmetry of the Universe from lepton flavor violation

Kyohei Mukaida, Kai Schmitz, Masaki Yamada

Charged-lepton flavor violation (CLFV) is a smoking-gun signature of physics beyond the Standard Model. The discovery of CLFV in upcoming experiments would indicate that CLFV proce…

EuCAPT White Paper: Opportunities and Challenges for Theoretical Astroparticle Physics in the Next Decade

R. Alves Batista, M. A. Amin, G. Barenboim +134

Astroparticle physics is undergoing a profound transformation, due to a series of extraordinary new results, such as the discovery of high-energy cosmic neutrinos with IceCube, the…

Gauge-field production during axion inflation in the gradient expansion formalism

E. V. Gorbar, K. Schmitz, O. O. Sobol +1

We study the explosive production of gauge fields during axion inflation in a novel gradient expansion formalism that describes the time evolution of a set of bilinear electromagne…

Stochastic gravitational-wave background from metastable cosmic strings

Wilfried Buchmuller, Valerie Domcke, Kai Schmitz

A metastable cosmic-string network is a generic consequence of many grand unified theories (GUTs) when combined with cosmic inflation. Metastable cosmic strings are not topological…

Cosmological Relaxation through the Dark Axion Portal

Valerie Domcke, Kai Schmitz, Tevong You

The dark axion portal is a coupling of an axion-like particle to a dark photon kinetically mixed with the visible photon. We show how this portal, when applied to the relaxion, can…
