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

We report the measurement of the one-dimensional charged kaon correlation functions using 600GeV/cΣ−, π− and 540GeV/cp beams from the SELEX (E781) experiment at the Fermilab Tevatron. K±K± correlation functions are studied for three transverse pair momentum, kT, ranges and parameterized by a Gaussia...

Beschreibung
Zusammenfassung:	We report the measurement of the one-dimensional charged kaon correlation functions using 600GeV/cΣ−, π− and 540GeV/cp beams from the SELEX (E781) experiment at the Fermilab Tevatron. K±K± 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.
