32. A Simple Model for the Glasma

Larry McLerran (BNL)

10/03/2015, 09:00

I discuss a simple description of the distribution of quarks and gluons in the Glasma. This is motivated by transport equation for over occupied systems.

18. The anomalous magnetic moment of the muon from lattice QCD

The anomalous magnetic moment of the muon, defined as the fractional difference of its gyromagnetic ratio from the naive value of 2, has been measured with an impressive accuracy of 0.54 parts per million in experiment (BNL E821), thus providing one of the most stringent tests of the Standard Model. Intriguingly, the experimentally measured anomaly disagrees by around 3 standard deviations...

35. Universality of the hard-loop action

Alina Czajka (Jan Kochanowski University)

The effective actions of gauge bosons, fermions and scalars, which are obtained within the hard-loop approximation, are shown to have unique forms for a whole class of gauge theories including QED, scalar QED, super QED, pure Yang-Mills, QCD, super Yang-Mills. The universality occurs irrespective of a field content of each theory and of variety of specific interactions. Consequently, the...

22. Refined lattice/model investigation of u d $\bar b \bar b$ tetraquark candidates with heavy spin effects taken into account

Jonas Benedict Scheunert (Goethe Universität Frankfurt)

We investigate four-quark systems consisting of two heavy anti-bottom quarks and two light up/down quarks. To this end we solve a coupled Schrödinger equation for the anti-bottom-anti-bottom separation using potentials computed via lattice QCD in the limit of static anti-bottom quarks. This coupled Schrödinger equation allows to incoporate effects due to the heavy anti-bottom spins.
