We report a measurement of the CP-violation parameter sin2Φ₁ at the Υ(5S) resonance using a new tagging method, called “B-_π tagging.” In Υ(5S) decays containing a neutral B meson, a charged B, and a charged pion, the neutral B is reconstructed in the J/ψK⁰_SCP-eigenstate decay channel. The initial flavor of the neutral B meson at the moment of the Υ(5S) decay is opposite to that of the charged B and may thus be inferred from the charge of the pion without reconstructing the charged B. From the asymmetry between B-_π⁺ and B_π⁻ tagged J/ψK⁰_S yields, we determine sin2Φ₁=0.57±0.58(stat)±0.06(syst). The results are based on 121 fb⁻¹ of data recorded by the Belle detector at the KEKB e⁺e⁻ collider.
