Abstract
If quarks are composite particles then excited states are expected. We have searched in ppBAR collisions for excited quarks (q*) which decay to common quarks by emitting a W boson (q* --> qW) or a photon (q* --> qgamma). The simplest model of excited quarks has been excluded for mass M* < 540 GeV/c2 at 95% confidence level. RI Chiarelli, Giorgio/E-8953-2012; Azzi, Patrizia/H-5404-2012File in questo prodotto:
