Revisiting the pentaquark episode for lattice QCD

Presenter: Abdullah Shams Bin Tariq — Rajshahi University, Bangladesh

The claimed observation of pentaquark states followed by seemingly conflicting sets of evidence from several experiments generated a good deal of interest. The evidence in favour of such states seems to be getting weaker. However, this episode has left behind interesting lessons in general, as well as for lattice QCD. This work examines some of the issues that came up and outlines limitations of and conditions for simulations of such states on the lattice.
