XHADRONS@ISTANBUL is the "1st International Workshop on Exotic Hadrons" to be held from September 3rd to 5th, 2015 at Mimar Sinan Fine Arts University, Main Building at Fındıklı. This workshop is organized to establish closer contacts between experimentalists and theorists involved in the studies of exotic hadrons such as X(3872), Y(4140) and Z(4430) mesons. The purpose is to provide an overview of the present status in these fields, as well as of new developments, and a preview of the forthcoming investigations. The workshop is open to experts and young researchers who are interested in the field. The workshop is even more interesting after that LHCb collaboration announced results that confirm the existence of pentaquarks.
