Abstract |
This paper presents the first measurement of the forward-backward asymmetry, AFB, and the flat term, F-H, that parameterise the angular distribution of the B+ -> pi(+)mu(+)mu(-) decay. The proton-proton collision dataset used in the analysis corresponds to an integrated luminosity of 9 fb(-1), collected with the LHCb experiment between 2011 and 2018. The analysis is performed in two intervals of dimuon mass squared, one above and one below the region containing the J/psi and psi(2S) narrow charmonium resonances. The Standard Model predictions lie within the obtained 68% confidence level interval in the high-mass and within the 99% interval in the low-mass region. |
