SIMULATeQCD: A simple multi-GPU lattice code for QCD calculations
Lukas Mazur, Dennis Bollweg, David A. Clarke +14
The rise of exascale supercomputers has fueled competition among GPU vendors, driving lattice QCD developers to write code that supports multiple APIs. Moreover, new developments i…
Baryonic states in supersymmetric SU(2) Yang-Mills theory on the lattice
Sajid Ali, Georg Bergner, Camilo Lopez +3
We extend our analysis of bound states in supersymmetric Yang-Mills theory by the consideration of baryonic operators, which are composed of three gluino fields. Th…
Study of charm and beauty in QGP from unquenched lattice QCD
Sajid Ali, Dibyendu Bala, Olaf Kaczmarek +2
We present charmonium and bottomonium correlators and corresponding reconstructed spectral functions from full QCD calculations in the pseudoscalar channel. Correlators are obtaine…
Photon production rate from Transverse-Longitudinal () mesonic correlator on the lattice
Dibyendu Bala, Sajid Ali, Anthony Francis +3
Thermal photons from the QGP provide important information about the interaction among plasma constituents. The photon production rate from a thermally equilibrated system is propo…
Estimates for the lightest baryon masses in supersymmetric Yang-Mills theory
Sajid Ali, Georg Bergner, Camilo Lopez +3
supersymmetric Yang-Mills theory describes gluons interacting with gluinos, which are spin- Majorana particles in the adjoint representation of the g…
Continuum extrapolation of Ward identities in supersymmetric SU(3) Yang-Mills theory
Sajid Ali, Georg Bergner, Henning Gerber +4
In supersymmetric Yang-Mills theory, regularised on a space-time lattice, in addition to the breaking by the gluino mass term, supersymmetry is broken explicitly by…
Continuum limit of SU(3) supersymmetric Yang-Mills theory and supersymmetric gauge theories on the lattice
Sajid Ali, Georg Bergner, Henning Gerber +5
We summarize our investigations of several aspects of supersymmetric Yang-Mills (SYM) theory. We present our final results for SU(3) SYM simulated w…
Numerical results for the lightest bound states in supersymmetric SU(3) Yang-Mills theory
Sajid Ali, Georg Bergner, Henning Gerber +4
The physical particles in supersymmetric Yang-Mills theory (SYM) are bound states of gluons and gluinos. We have determined the masses of the lightest bound states in SU(3) $\mathc…
Variational analysis of low-lying states in supersymmetric Yang-Mills theory
Sajid Ali, Georg Bergner, Henning Gerber +5
We have calculated the masses of bound states numerically in N = 1 supersymmetric Yang-Mills theory with gauge group SU(2). Using the suitably optimised variational method with an…

Sajid Ali, Georg Bergner, Henning Gerber +5
In =1 supersymmetric Yang-Mills theory the superpartner of the gluon is the gluino, which is a spin 1/2 Majorana particle in the adjoint representation of the gauge gr…
Analysis of Ward identities in supersymmetric Yang-Mills theory
Sajid Ali, Georg Bergner, Henning Gerber +4
In numerical investigations of supersymmetric Yang-Mills theory on a lattice, the supersymmetric Ward identities are valuable for finding the critical value of the hopping paramete…
The light bound states of supersymmetric SU(3) Yang-Mills theory on the lattice
Sajid Ali, Georg Bergner, Henning Gerber +5
In this article we summarise our results from numerical simulations of supersymmetric Yang-Mills theory with gauge group SU(3). We use the formulation of Curci and…
Ward identities in supersymmetric SU(3) Yang-Mills theory on the lattice
Sajid Ali, Georg Bergner, Henning Gerber +5
The introduction of a space-time lattice as a regulator of field theories breaks symmetries associated with continuous space-time, i.e.\ Poincar{é} invariance and supersymmetry. A…
Supermultiplets in N=1 SUSY SU(2) Yang-Mills Theory
