Abstract
DESY-HERA. Study of Jet Shapes produced in quasi-real photon-proton collisions at centre-of-mass energies in the range 134 to 227 GeV. Jets are identified using a cone alogrithm in the eta-phi plane with a cone radius of one unit. The jet shape parameter PSI(R) is defined as the average fraction of the jet& apos;s transverse energy (ET) that is within an inner cone of radius R concentric with the jet defining cone (R=1). Data are given for both inclusive jet production and dijet production with jets having ET & gt; 14 GeV. All data are corrected to the hadron level. Numerical values supplied by Claudia Glasman.
