Measurement of the Dihadron Mass Continuum inp-Be Collisions and a Search for Narrow Resonances

Abstract

We have studied the high-mass dihadron continuum in 400-GeV $p$-Be collisions over the mass range 4-10 GeV. The experiment was performed at Fermilab using a double arm magnetic spectrometer including Čerenkov particle identification. Mass spectra for all combinations formed with an identified ${\pi }^{\pm }$, $K^{\pm }$, or $p\left(\overline{p}\right)$ in each arm have been examined. No evidence for resonance production was observed. Results on mass and $p_T$ dependence of the dihadron inclusive cross sections are presented.
