Description
Two-particle correlations at low relative momentum
provide information on the space-time geometry of
emitting sources on the femtoscopic scale.
Dynamical properties of the system are reflected
in the total pair momentum dependence of the correlations.
We present a preliminary measurement of the multiplicity
and transverse momentum dependence of charged kaon
correlations at small relative momentum measured in $p+p$
collisions by the STAR detector at RHIC. Using kaons
allows for the study of the emitting source radii to
be extended to higher values of transverse mass.
Results are presented for $\sqrt{s}=200$ and
$\sqrt{s}=510$ GeV and compared to similar measurements
recently reported at the LHC.
