The determination of the phase diagram of QCD as a function of temperature and chemical potential via lattice simulations remains a challenge. This is because
of the "sign problem" at non-zero matter density. I want to highlight some
recent progress, both technical and analytical, which may bring reliable
answers soon.
One of the most promising quantities for the search of signatures of physics beyond the Standard Model is the anomalous magnetic moment g-2 of the muon, where a comparison of the experimental result with the Standard Model estimate yields a deviation of about 3.5 sigma. On the theory side, the largest uncertainty arises from the hadronic sector, namely the hadronic vacuum polarisation and the...
We discuss two implementations of the recently developed density of states functional fit approach (DoS FFA) to lattice QCD at finite density. Both implementations are based on suitable pseudo-fermion representations of lattice QCD. The first approach identifies the imaginary part of the pseudo-fermion action in the grand-canonical picture and treats it with a direct application of DoS FFA....
The present status of quark flavour physics, both in the Delta F=1 and Delta F=2 sectors, is reviewed. Possible theoretical implications of present experimental data are discussed and the impact of future experiments is assessed for some observables of interest.
