DESCRIPTION:Speakers: Ulrich Wiedner (---)\n\nWhile the Higgs mechanism mi
 ght be responsible for the masses of the elementary particles\, the mass-c
 reation mechanism for hadrons is quite different. Less than 1% percent of 
 the mass of the proton is due to the Higgs mechanism. Particles solely com
 posed of gluons are at the center of the strong intera ction. Glueballs th
 emselves would be massless without the strong interaction and their predic
 ted masses arise solely from the strong interaction. Glueballs thus offer 
 a unique way to study the mass creation of strongly interacting particles.
  In the past years\, a new relation between modern superstring theory and 
 QCD has been developed by the AdS/CFT (Anti-de Sitter space / conformal fi
 eld theory) correspondence. Several groups have studied in the Witten-Saka
 i-Sugimoto model of strings to investigate glueballs and their behavior. M
 odern stringy hadron models attempt not only to make predictions for glueb
 alls but also describe and predict other hadronic states including their d
 ecay dynamics. This talk describes the experimental situation and the expe
 rimental perspectives to provide more information on glueballs and their s
 tructure.\n\nhttps://indico.gsi.de/event/25015/
