The transverse momentum dependence of charged kaon Bose–Einstein correlations in the SELEX experiment

We report on the measurement of the charged kaon correlation functions kT dependencies using 600 GeV/c , and 540 GeV/c p beams from the SELEX (E781) experiment at Tevatron. One-dimensional K ch K ch correlation functions are constructed in three transverse momentum ranges. The emission source parameters and R are extracted. The analysis shows a decrease of the source radii with the kaon pair transverse momentum for all beam types.
