Scaling behaviour of exclusive reactions with the deuteron and 3He at high p_T in the Gev region
Abstract
Description
The scaling behaviour s^{-11} of the cross section of the reaction γd-> pn observed at SLAC and Jlab at energies E_γ=1-4 GeV and large p_T most likely displays quark degrees of freedom in the deuteron. We show that the cross sections of the dd->3Hp and pd-> 3Hen reactions measured at SATURNE follow the scaling regime s{-22} at T_d= 0.5 -1.2 GeV and $θ_{cm}=50^\circ-60^\circ$. A necessity to get new data on this and other exclusive reactions is argued.
