Right-handed neutrino production rate at T > 160 GeV

- I. Ghişoiu, M. Laine
- Physics
- 6 November 2014

The production rate of right-handed neutrinos from a Standard Model plasma at a temperature above a hundred GeV has previously been evaluated up to NLO in Standard Model couplings (g ∼ 2/3) in… Expand

A new method for taming tensor sum-integrals

- I. Ghişoiu, Y. Schröder
- Physics
- 1 August 2012

A bstractWe report on the computation of a class of massless bosonic three-loop vacuum sum-integrals which are key building blocks for an evaluation of the Debye screening mass in hot QCD.… Expand

Interpolation of hard and soft dilepton rates

- I. Ghişoiu, M. Laine
- Physics
- 30 July 2014

A bstractStrict next-to-leading order (NLO) results for the dilepton production rate from a QCD plasma at temperatures above a few hundred MeV suffer from a breakdown of the loop expansion in the… Expand

Tight-binding molecular dynamics simulations of radiation-induced C 60 fragmentation

- T. Beu, L. Horváth, I. Ghişoiu
- Physics
- 26 February 2009

The radiation-induced fragmentation of the ${\text{C}}_{60}$ fullerene was investigated by tight-binding molecular dynamics simulations based on the parametrization of Papaconstantopoulos et al.… Expand

Debye screening mass of hot Yang-Mills theory to three-loop order

- I. Ghişoiu, J. Möller, Y. Schröder
- Physics
- 29 September 2015

A bstractBuilding upon our earlier work, we compute a Debye mass of finite-temperature Yang-Mills theory to three-loop order. As an application, we determine a g7 contribution to the thermodynamic… Expand

Three-loop Debye mass and effective coupling in thermal QCD

- I. Ghişoiu
- Physics
- 2013

We determine the three-loop effective parameters of the dimensionally reduced theory of EQCD as matching coefficients to full QCD. The mass parameter $\mE$ is interpreted as the high temperature,… Expand

On high-order perturbative calculations at finite density

- I. Ghişoiu, Tyler Gorda, A. Kurkela, P. Romatschke, Matias Sappi, A. Vuorinen
- Physics
- 14 September 2016

Abstract We discuss the prospects of performing high-order perturbative calculations in systems characterized by a vanishing temperature but finite density. In particular, we show that the… Expand

A new three-loop sum-integral of mass dimension two

- I. Ghişoiu, Y. Schröder
- Physics
- 26 July 2012

A bstractWe evaluate a new 3-loop sum-integral which contributes to the Debye screening mass in hot QCD. While we manage to derive all divergences analytically, its finite part is mapped onto simple… Expand
