We present an update of BQCD, our Hybrid Monte Carlo program for simulating lattice QCD. BQCD is one of the main production codes of the QCDSF collaboration and is used by CSSM and in some Japanese finite temperature and finite density projects. Since the first publication of the code at Lattice 2010 the program has been extended in various ways. New features of the code include: dynamical QED, action modification in order to compute matrix elements by using Feynman-Hellman theory, more trace measurements, a more flexible integration scheme, polynomial filtering, term-splitting for RHMC, and a portable implementation of performance critical parts employing SIMD.

Discussion (0). Continue with ORCID to comment.

  1. Patterns of flavour symmetry breaking in hadron matrix elements involving u, d and s quarks

    hep-lat 2019-09 conditional novelty 6.0 of 10

    Octet baryon matrix elements of octet currents obey a constrained SU(3) flavour-breaking expansion along the constant-singlet-mass trajectory, with one constraint at second order and no further constraints at third or...

  2. Transverse force distributions in the proton from lattice QCD

    hep-lat 2025-02 conditional novelty 5.0 of 10

    Lattice QCD computes the transverse spatial distribution of the colour-Lorentz force on the struck quark in a proton, finding local forces up to about 3 GeV/fm, larger than the QCD string tension.

  3. Renormalisation Group Equations for 2+1 clover fermions

    hep-lat 2025-01 conditional novelty 5.0 of 10

    The authors derive and apply RG equations for the lattice spacing in 2+1 clover fermion QCD, finding only a small quark mass dependence and smoother lattice spacing ratios.
