Diffractive dissociation of exclusive K π+ π events in the high energetic hadron beam of the COMPASS-experiment — •Prometeusz Jasinski — Institut für Kernphysik, Universität Mainz, Johann-Joachim-Becherweg 45, 55099 Mainz

In order to study the production of exotic mesons the COMPASS experiment at CERN took data with a 190 GeV/c hadron beam hitting a liquid hydrogen target in the years 2008 and 2009. The negative hadron beam contains mainly pions and a small fraction of about 2.5% of kaons. Using CEDAR pid detectors in the beam line we are identifying the small kaon component. One of the channels of interest are diffractively produced resonances decaying into K π+ π final states. I will deliver insight to ongoing analysis of this channel that is of major interest for not well explored K resonances such as K2(1820) and K(1460).
