Magnetogenesis in Higgs-Starobinsky inflation

In the framework of mixed Higgs-Starobinsky inflation, we consider the generation of Abelian gauge fields due to their nonminimal coupling to gravity (in two different formulations of gravity-metric and Palatini). We couple the gauge-field invariants F mu ...

Standard model meets gravity: Electroweak symmetry breaking and inflation

Andrey Shkerin, Sebastian Zell

We propose a model for combining the Standard Model (SM) with gravity. It relies on a nonminimal coupling of the Higgs field to the Ricci scalar and on the Palatini formulation of gravity. Without introducing any new degrees of freedom in addition to those ...

The role of demand in fostering product vs process innovation: a model and an empirical test

Gabriele Pellegrino

While the extant innovation literature has provided extensive evidence of the so-called "demand-pull" effect, the possible diverse impact of demand evolution on product vs process innovation activities has not been yet investigated. This paper develops a f ...

Monopsony with nominal rigidities: An inverted Phillips Curve

Charles Cosme Henri Dennery

With nominal wage rigidities, it is crucial to distinguish whether wages are set by workers or firms — whether we have monopoly or monopsony power. This paper provides a model of monopsony power in the labour market and a monopsonistic Phillips Curve. If w ...

Dampened expectations in the Phillips Curve: A note

Charles Cosme Henri Dennery

Dampened inflation expectations have a significant impact on the New Keynesian Phillips Curve. This dampening not only flattens the long run Phillips Curve, but it can also lead to a bias in the estimation of its short run slope. It also affects the respon ...

Backreaction of electromagnetic fields and the Schwinger effect in pseudoscalar inflation magnetogenesis

Oleksandr Sobol

We study magnetogenesis in axionlike inflation driven by a pseudoscalar field phi coupled axially to the electromagnetic (EM) field (beta/M-p)phi F-mu nu(F) over tilde mu nu with dimensionless coupling constant beta. A set of equations for the inflaton fie ...

Asymmetric dark matter and baryogenesis from pseudoscalar inflation

Eray Sabancilar, Yann David Cado

We show that both the baryon asymmetry of the Universe and the dark matter abundance can be explained within a single framework that makes use of maximally helical hypermagnetic fields produced during pseudoscalar inflation and the chiral anomaly in the St ...

Living beyond the edge: Higgs inflation and vacuum metastability

Javier Rubio

The measurements of the Higgs mass and top Yukawa coupling indicate that we live in a very special universe, at the edge of the absolute stability of the electroweak vacuum. If fully stable, the Standard Model (SM) can be extended all the way up to the inf ...

On the strong coupling scale in Higgs G-inflation

Kohei Kamada

Higgs G-inflation is an inflation model that takes advantage of a Galileon-like derivative coupling. It is a non-renormalizable operator and is strongly coupled at high energy scales. Perturbative analysis does not have a predictive power any longer there. ...

Inflation, LHC and the Higgs boson

After the Higgs boson has been discovered, the Standard Model of particle physics became a confirmed theory, potentially valid up to the Planck scale and allowing to trace the evolution of the Universe from inflationary stage till the present days. We disc ...
