A Lattice Calculation of Parton Distributions
Constantia Alexandrou, Krzysztof Cichy, Vincent Drach +5
We report on our exploratory study for the direct evaluation of the parton distribution functions from lattice QCD, based on a recently proposed new approach. We present encouragin…
First moment of the flavour octet nucleon parton distribution function using lattice QCD
C. Alexandrou, M. Constantinou, S. Dinter +5
We perform a lattice computation of the flavour octet contribution to the average quark momentum in a nucleon, $\la x\ra^{(8)}_{μ^2 = 4 \gev^2}$. In particular, we fully take the d…
Real-time dynamics of open quantum spin systems driven by dissipative processes
Florian Hebenstreit, Debasish Banerjee, Manes Hornung +3
We study the real-time evolution of large open quantum spin systems in two spatial dimensions, whose dynamics is entirely driven by a dissipative coupling to the environment. We co…
A lattice study of a chirally invariant Higgs-Yukawa model including a higher dimensional -term
David Y. -J. Chu, Karl Jansen, Bastian Knippschild +2
We discuss the non-thermal phase structure of a chirally invariant Higgs-Yukawa model on the lattice in the presence of a higher dimensional -term. For the exploration of the…
