Search for B0->phiK+pi- Decays with Large K+pi- Invariant Mass

Understand

Motivated by the polarization anomaly in the B->phi(1020)K*(892) decay, we extend our search for other K* final states in the decay B0->phi(1020)K^*0 with the K*0->K+pi- invariant mass above 1.6 GeV.

• The final states considered include the K*(1680)0, K3*(1780)0, K4*(2045)0, and a Kpi spin-zero nonresonant component.
• We also search for B0->phiDbar0 decay with the same final state.
• The analysis is based on a sample of about 384 million BBbar pairs recorded with the BABAR detector.
