Abstract

We perform an angular analysis of the B→K∗e+e- decay for the dielectron mass squared, q2, range of 0.0008-1.1200 GeV2/c4 using the full Belle dataset in the K∗0→K+π- and K∗+→KS0π+ channels, incorporating new methods of electron identification to improve the statistical power of the dataset. This analysis is sensitive to contributions from right-handed currents from physics beyond the Standard Model by constraining the Wilson coefficients C7(′). We perform a fit to the B→K∗e+e- differential decay rate and measure the imaginary component of the transversality amplitude to be ATIm=-1.27±0.52±0.12, and the K∗ transverse asymmetry to be AT(2)=0.52±0.53±0.11, with FL and ATRe fixed to the Standard Model values. The resulting constraints on the value of C7′ are consistent with the Standard Model within a 2σ confidence interval.

N2 - We perform an angular analysis of the B→K∗e+e- decay for the dielectron mass squared, q2, range of 0.0008-1.1200 GeV2/c4 using the full Belle dataset in the K∗0→K+π- and K∗+→KS0π+ channels, incorporating new methods of electron identification to improve the statistical power of the dataset. This analysis is sensitive to contributions from right-handed currents from physics beyond the Standard Model by constraining the Wilson coefficients C7(′). We perform a fit to the B→K∗e+e- differential decay rate and measure the imaginary component of the transversality amplitude to be ATIm=-1.27±0.52±0.12, and the K∗ transverse asymmetry to be AT(2)=0.52±0.53±0.11, with FL and ATRe fixed to the Standard Model values. The resulting constraints on the value of C7′ are consistent with the Standard Model within a 2σ confidence interval.
