The transverse momentum dependence of charged kaon Bose-Einstein correlations in the SELEX experiment
Abstract
We report on the measurement of the one-dimensional charged kaon correlation functions using 600~GeV/ c -, π- and 540~GeV/ c p beams from the SELEX~(E781) experiment at the Fermilab Tevatron. KK correlation functions are studied for three transverse pair momentum, kT, ranges and parameterized by a Gaussian form. The emission source radii, R, and the correlation strength, λ, are extracted. The analysis shows a decrease of the source radii with increasing kaon transverse pair momentum for all beam types.
