Collective modes and instabilities in anisotropically expanding ultarelativistic plasmas
Anton Rebhan, Dominik Steineder
The time evolution of collective modes in an expanding ultarelativistic and (effectively) Abelian plasma is studied in the hard-loop approximation semi-analytically by means of int…
The N_f^3 g^6 term in the pressure of hot QCD
A. Gynther, A. Kurkela, A. Vuorinen
We determine the first independent part of the g^6 coefficient in the weak coupling expansion of the QCD pressure at high temperatures, the one proportional to the maximal power of…
On Continuum-State and Bound-State Beta Decay Rates of the Neutron
M. Faber, A. N. Ivanov, V. A. Ivanova +5
We analyse the continuum-state and bound-state beta^-decay rates of the neutron. For the calculation of theoretical values of the decay rates we use the new value for the axial cou…
On the imaginary part of the next-to-leading-order static gluon self-energy in an anisotropic plasma
M. E. Carrington, A. Rebhan
Using hard-loop (HL) effective theory for an anisotropic non-Abelian plasma, which even in the static limit involves nonvanishing HL vertices, we calculate the imaginary part of th…
On the dispersion of fundamental particles in QCD and N=4 Super Yang-Mills theory
P. M. Chesler, A. Gynther, A. Vuorinen
We study thermal corrections to the dispersion relations of massive fundamental particles immersed in weakly coupled non-Abelian plasmas. The cases covered include quarks in the QC…
On Continuum- and Bound-State l^- Decay Rates of Pionic and Kaonic Hydrogen in the Ground State
M. Faber, A. N. Ivanov, V. A. Ivanova +4
We calculate the continuum- and bound-state l^- decay rates of pionic and kaonic hydrogen in the ground state, where l^- is either the electron or the muon.
