A search is made for the highly-suppressed B meson decays B+âK+K+Ïâand B+âÏ+Ï+Kâusing a data sample corresponding to an integrated luminosity of 3.0âfbâ1collected by the LHCb experiment in protonâproton collisions at centre-of-mass energies of 7 and 8 TeV. No evidence is found for the decays, and upper limits at 90% confidence level are determined to be B(B+âK+K+Ïâ)<1.1�10â8and B(B+âÏ+Ï+Kâ)<4.6�10â8.

Abstract
A search is made for the highly-suppressed B meson decays B+âK+K+Ïâand B+âÏ+Ï+Kâusing a data sample corresponding to an integrated luminosity of 3.0âfbâ1collected by the LHCb experiment in protonâproton collisions at centre-of-mass energies of 7 and 8 TeV. No evidence is found for the decays, and upper limits at 90% confidence level are determined to be B(B+âK+K+Ïâ)<1.1�10â8and B(B+âÏ+Ï+Kâ)<4.6�10â8.File in questo prodotto:
