Thermal gravitino and axino rate from AutoTherm
Killian Bouzoud, Jacopo Ghiglieri, Greg Jackson
If ultrarelativistic supersymmetric particles are thermally produced in the early universe they would influence big-bang nucleosynthesis, dark matter and reheating constraints. Whi…
AutoTherm: Automated Thermal Field Theory rates for cosmology
Killian Bouzoud, Jacopo Ghiglieri, Greg Jackson
AutoTherm is a modular code automating the determination of thermal production and interaction rates for cosmology from Thermal Field Theory. This first release computes fully auto…
Energy and momentum dependence of the soft-axion interaction rate
Killian Bouzoud, Jacopo Ghiglieri, M. Laine +1
Axions coupled to thermal non-Abelian gauge fields may have cosmological significance. As the heat bath defines a frame, its influence depends separately on energy and momentum. A…
Thermal axion production at hard and soft momenta
Killian Bouzoud, Jacopo Ghiglieri
Hot axions, thermally produced in the Early Universe, would contribute to dark radiation and are thus subject to present and future constraints from . In this paper we…
Double-graviton production from Standard Model plasma
J. Ghiglieri, M. Laine, J. Schütte-Engel +1
The thermal plasma filling the early universe generated a stochastic gravitational wave background that peaks in the microwave frequency range today. If the graviton production rat…
The force-force correlator at the hard thermal scale of hot QCD
Jacopo Ghiglieri, Philipp Schicho, Niels Schlusser +1
High-energy particles traversing the Quark-Gluon plasma experience modified (massive) dispersion, although their vacuum mass is negligible compared to the kinetic energy. Due to po…
Hard parton dispersion in the quark-gluon plasma, non-perturbatively
Jacopo Ghiglieri, Guy D. Moore, Philipp Schicho +2
The in-medium dispersion of hard partons, encoded in their so-called asymptotic mass, receives large non-perturbative contributions from classical gluons, i.e. soft gluons with lar…
Freezing-In Gravitational Waves
Jacopo Ghiglieri, Jan Schütte-Engel, Enrico Speranza
The thermal plasma in the early universe produced a stochastic gravitational wave (GW) background, which peaks today in the microwave regime and was dubbed the cosmic gravitational…
Thermalization of weakly coupled non-Abelian plasmas at next-to-leading order
Yu Fu, Jacopo Ghiglieri, Shahin Iqbal +1
We employ the QCD kinetic theory, including next-to-leading(NLO) order corrections in coupling constant, to study the evolution of weakly coupled non-Abelian plasmas towards therma…
Transport properties of the QCD medium
Jacopo Ghiglieri
I present an overview of recent developments in the microscopic description of the quark-gluon plasma. I will concentrate on medium-induced emission and transverse momentum broaden…
Classical vs quantum corrections to jet broadening in a weakly-coupled Quark-Gluon Plasma
Jacopo Ghiglieri, Eamonn Weitz
The transverse momentum broadening coefficient receives both soft, classical and radiative, quantum corrections. The former are responsible for a large O(g) correction, w…
Theories and Experiments for Testable Baryogenesis Mechanisms: A Snowmass White Paper
J. L. Barrow, Leah Broussard, James M. Cline +16
The baryon asymmetry of the Universe is one of the central motivations to expect physics beyond the Standard Model. In this Snowmass white paper, we review the challenges and oppor…
The force-force-correlator in hot QCD perturbatively and from the lattice
Jacopo Ghiglieri, Guy D. Moore, Philipp Schicho +1
High-energy particles traversing a medium experience modified dispersion. In the Quark-Gluon Plasma, such dispersion affects jet propagation and transport properties and should be…
Smooth interpolation between thermal Born and LPM rates
J. Ghiglieri, M. Laine
In a weakly coupled ultrarelativistic plasma, scatterings, with , need sometimes to be summed to all orders, in order to determine a leading-…
Thermalization of non-abelian gauge theories at next-to-leading order
Yu Fu, Jacopo Ghiglieri, Shahin Iqbal +1
We provide the first next-to-leading-order (NLO) weak-coupling description of the thermalization process of far-from-equilibrium systems in non-abelian gauge theory. We study isotr…
Freeze-in produced dark matter in the ultra-relativistic regime
Simone Biondini, Jacopo Ghiglieri
When dark matter particles only feebly interact with plasma constituents in the early universe, they never reach thermal equilibrium. As opposed to the freeze-out mechanism, where…
Gravitational wave background from Standard Model physics: Complete leading order
J. Ghiglieri, G. Jackson, M. Laine +1
We compute the production rate of the energy density carried by gravitational waves emitted by a Standard Model plasma in thermal equilibrium, consistently to leading order in coup…
Sterile neutrino dark matter via coinciding resonances
J. Ghiglieri, M. Laine
It has been proposed that two resonances could coincide in the early universe at temperatures GeV: one between two nearly degenerate GeV-scale sterile neutrino…
Perturbative Thermal QCD: Formalism and Applications
Jacopo Ghiglieri, Aleksi Kurkela, Michael Strickland +1
In this review article, we discuss the current status and future prospects of perturbation theory as a means of studying the equilibrium thermodynamic and near-equilibrium transpor…
Thermal Heavy Quark Self-Energy from Euclidean Correlators
Alexander M. Eller, Jacopo Ghiglieri, Guy D. Moore
Brambilla, Escobedo, Soto, and Vairo have derived an effective description of quarkonium with two parameters; a momentum diffusion term and a real self-energy term. We point out th…
Thermal width of the Higgs boson in hot QCD matter
Jacopo Ghiglieri, Urs Achim Wiedemann
Following Caron-Huot and combining results for the thermal dependence of spectral functions at large time-like momenta, we write an explicit expression for the thermal width of the…
Precision study of GeV-scale resonant leptogenesis
J. Ghiglieri, M. Laine
Low-scale leptogenesis is most efficient in the limit of an extreme mass degeneracy of right-handed neutrino flavours. Two variants of this situation are of particular interest: la…
Transverse momentum broadening and collinear radiation at NLO in the SYM plasma
Jacopo Ghiglieri, HyungJoo Kim
We compute O(g) NLO corrections to the transverse scattering kernel and transverse momentum broadening coefficient of weakly-coupled SYM. Based on this, w…
Second-order Hydrodynamics in Next-to-Leading-Order QCD
