Abstract

We report the measurement of the one-dimensional charged kaon correlation functions using 600 GeV/c Sigma(-), pi(-) and 540 GeV/c p beams from the SELEX (E781) experiment at the Fermilab Tevatron. (KK +/-)-K-+/- correlation functions are studied for three transverse pair momentum, k(T), ranges and parameterized by a Gaussian form. The emission source radii, R, and the correlation strength, lambda, are extracted. The analysis shows a decrease of the source radii with increasing kaon transverse pair momentum for all beam types.
