Matching QCD and HQET heavy-light currents at three loops
S. Bekavac, A. G. Grozin, P. Marquard +3
We consider the currents formed by a heavy and a light quark within Quantum Chromodynamics and compute the matching to Heavy Quark Effective Theory to three-loop accuracy. As an ap…
Light quark mass effects in the chromomagnetic moment
S. Bekavac, A. Grozin, D. Seidel +1
We present the three-loop QCD corrections to the quark chromomagnetic moment including two different nonzero masses. This is a necessary ingredient to obtain the corresponding corr…
Completely automated computation of the heavy-fermion corrections to the three-loop matching coefficient of the vector current
P. Marquard, J. H. Piclum, D. Seidel +1
We evaluate the corrections to the matching coefficient of the vector current between Quantum Chromodynamics (QCD) and Non-Relativistic QCD (NRQCD) to three-loop order containing a…
Three-loop on-shell Feynman integrals with two masses
S. Bekavac, A. G. Grozin, D. Seidel +1
All three-loop on-shell QCD Feynman integrals with two masses can be reduced to 27 master integrals. Here we calculate these master integrals, expanded in epsilon, both exactly in…
Threshold corrections to the gamma t anti-t vertex at O(alpha alpha(s))
Dirk Seidel
In these proceedings a recent calculation of the last missing piece of the two-loop O(alpha alpha(s)) corrections to gamma t anti-t vertex at the t anti-t threshold due to the exch…
Dwell-time distributions in quantum mechanics
J. Muñoz, I. L. Egusquiza, A. del Campo +2
Some fundamental and formal aspects of the quantum dwell time are reviewed, examples for free motion and scattering off a potential barrier are provided, as well as extensions of t…
