  Title First Observation of CP Violation and Measurement of Polarization in B+ → ρ(770)0K*(892)+ Decays Type Journal Article
  Year 2026 Publication Physical Review Letters Abbreviated Journal Phys. Rev. Lett.  
  Volume 136 Issue 2 Pages 021803 - 16pp  
  Keywords  
  Abstract An amplitude analysis of the B+ -> (pi(+)pi(-))(K-S(0)pi(+)) decay is performed in the mass regions 0.30 < m pi(+)pi(-) < 1.10 GeV/c(2) and 0.75 < m(KS)(pi+)(0) < 1.20 GeV/c(2), using pp collision data recorded with the LHCb detector corresponding to an integrated luminosity of 9 fb-1. The polarization fractions and CP asymmetries for B+ -> rho(770)K-0*(892)(+) decays are measured. Violation of the CP symmetry in the decay B+ -> rho(770)K-0*(892)(+) is observed for the first time, with a significance exceeding 9 standard deviations. The CP asymmetry is measured to be A(CP) = 0.507 +/- 0.062(stat) +/- 0.024(syst) and the CP-averaged longitudinal polarization fraction of f(L) = 0.720 +/- 0.028(stat) +/- 0.009(syst). The measurements help to shed light on the polarization puzzle of B mesons decaying to two vector mesons.
