Thermal right-handed neutrino production rate in the non-relativistic regime

- M. Laine, Y. Schröder
- Physics
- 6 December 2011

A bstractWe consider the next-to-leading order thermal production rate of heavy right-handed neutrinos in the non-relativistic regime mtop ≲ πT ≪ M, where mtop refers to the electroweak scale.… Expand

Five-loop quark mass and field anomalous dimensions for a general gauge group

- T. Luthe, A. Maier, P. Marquard, Y. Schröder
- Physics
- 16 December 2016

A bstractWe present analytical five-loop results for the quark mass and quark field anomalous dimensions, for a general gauge group and in the MS¯$$ \overline{\mathrm{MS}} $$ scheme. We confirm the… 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

The five-loop Beta function for a general gauge group and anomalous dimensions beyond Feynman gauge

- T. Luthe, A. Maier, P. Marquard, Y. Schröder
- Physics
- 22 September 2017

A bstractWe focus on a non-abelian gauge field coupled to a single (but general) representation of a family of Nf fermions. By using the same machinery that had allowed us to evaluate the sub-leading… Expand

The Static potential in QCD to two loops

- Y. Schröder
- Physics
- 11 February 1999

We evaluate the static QCD potential to two--loop order. Compared to a previous calculation a sizable reduction of the two--loop coefficient $a_2$ is found.

Complete renormalization of QCD at five loops

- T. Luthe, A. Maier, P. Marquard, Y. Schröder
- Physics
- 24 January 2017

A bstractWe present new analytical five-loop Feynman-gauge results for the anomalous dimensions of ghost field and -vertex, generalizing the known values for SU(3) to a general gauge group. Together… Expand

Long-distance contributions to the QCD pressure

- Y. Schröder
- Physics
- 6 May 2002

The QCD pressure is a most fundamental quantity, for which lattice data is available up to a few times the critical temperature $T_c$. Perturbation theory, even at very high temperatures, has serious… Expand

Loops for Hot QCD

- Y. Schröder
- Physics
- 1 October 2008

In this talk we review the status concerning vacuum integrals needed in perturbative expansions of QCD at non-zero temperature. We will focus on the differences as compared to familiar… Expand

Soft thermal contributions to 3-loop gauge coupling

- M. Laine, P. Schicho, Y. Schröder
- Physics
- 23 March 2018

A bstractWe analyze 3-loop contributions to the gauge coupling felt by ultrasoft (“magnetostatic”) modes in hot Yang-Mills theory. So-called soft/hard terms, originating from dimension-six operators… Expand

The ultraviolet limit and sum rule for the shear correlator in hot Yang-Mills theory

- Y. Schröder, M. Vepsäläinen, A. Vuorinen, Y. Zhu
- Physics
- 29 September 2011

We determine a next-to-leading order result for the correlator of the shear stress operator in high-temperature Yang-Mills theory. The computation is performed via an ultraviolet expansion, valid in… Expand
