Computation of correlation matrices for tetraquark candidates with Jp = 0+ and flavor structure q1q2q3q3
Berlin, J.; Abdel-Rehim, A.; Alexandrou, Constantia; Dalla Brida, M.; Gravina, M.; Wagner, M. (Proceedings of Science (PoS), 2015)The conjecture that several recently observed mesons have a structure, which is not dominated by an ordinary quark-Antiquark pair, but by a four-quark structure, is being actively investigated both theoretical and ...

Investigating efficient methods for computing four-quark correlation functions
Abdel-Rehim, A.; Alexandrou, Constantia; Berlin, J.; Dalla Brida, M.; Finkenrath, J.; Wagner, M. (2017)We discuss and compare the efficiency of various methods, combinations of point-to-all propagators, stochastic timeslice-to-all propagators, the one-end trick and sequential propagators, to compute two-point correlation ...
