Abstract:	The process ???ppK+K- and its intermediate processes are measured for the first time using a 980 fb-1 data sample collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. The production of ppK+K- and a ?(1520)0 (?(1520)0) signal in the pK- (pK+) invariant mass spectrum are clearly observed. However, no evidence for an exotic baryon near 1540 MeV/c2, denoted as ?(1540)0 (?(1540)0) or ?(1540)++ (?(1540) - ), is seen in the pK- (pK+) or pK+ (pK-) invariant mass spectra. Cross sections for ???ppK+K-, ?(1520)0pK++c.c. and the products ?(????(1540)0pK++c.c.)B(?(1540)0?pK-) and ?(????(1540)++pK-+c.c.)B(?(1540)++?pK+) are measured. We also determine upper limits on the products of the ?c0 and ?c2 two-photon decay widths and their branching fractions to ppK+K- at the 90% credibility level. � 2016 American Physical Society.
