The Bodmer-Witten hypothesis concerns the possibility that ordinary hadronic matter in bulk is a metastable state of strongly interacting matter, while strange quark matter (SQM) is absolutely stable (i.e., the global minimum). These two phases would be separated by a potential barrier that prevents the spontaneous decay of hadronic matter into SQM in ordinary conditions.
If this hypothesis...
The homogeneous Bethe-Salpeter equation (hBSE) [1], which models a bound system within a fully relativistic quantum field theory, has been solved for the first time using a D-Wave quantum annealer [2]. Following standard discretization methods, the hBSE in the ladder approximation can be reformulated as a generalized eigenvalue problem (GEVP) involving two square matrices, one symmetric and...
Collider-based QCD calculations shed light on cosmic ray antiproton anomalies with novel cross-disciplinary results. Current astrophysical observations require a precise calculation of cross sections for direct proton-proton to antiproton production vs. indirect production (in which an antineutron is produced first and decays to an antiproton with branching ratio 1). The results of cross...
