On the spectrum and string tension of U(1) lattice gauge theory in 2+1 dimensions
Andreas Athenodorou, Michael Teper
We calculate the low-lying spectra of glueballs and confining flux tubes in the U(1) lattice gauge theory in 2+1 dimensions. We see that up to modest lattice spacing corrections, t…
Instanton based importance sampling for rare events in stochastic PDEs
Lasse Ebener, Georgios Margazoglou, Jan Friedrich +2
We present a new method for sampling rare and large fluctuations in a non-equilibrium system governed by a stochastic partial differential equation (SPDE) with additive forcing. To…
Proton and neutron electromagnetic form factors from lattice QCD
C. Alexandrou, S. Bacchio, M. Constantinou +5
The electromagnetic form factors of the proton and the neutron are computed within lattice QCD using simulations with quarks masses fixed to their physical values. Both connected a…
Calculating the radiative decay width with lattice QCD
Luka Leskovec, Constantia Alexandrou, Stefan Meinel +6
We present the results of our lattice QCD study of the process, where the resonance appears as an enhancement in the transition amplitude. We use clover fer…
Quasi-PDFs from Twisted mass fermions at the physical point
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +4
We present results for the flavor non-singlet u-d parton distribution functions within the nucleon using the quasi-PDF approach. The lattice calculation is performed by employing t…
Light-cone PDFs from Lattice QCD
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +4
Using the approach proposed a few years ago by X. Ji, it has become feasible to extract parton distribution functions (PDFs) from lattice QCD, a task thought to be extremely diffic…
