Measurements of the polarisation amplitudes and triple product asymmetries in B_s^0 to phi phi

TL;DR

This paper reports measurements of polarization amplitudes and triple product asymmetries in the decay B_s^0 to phi phi using LHCb data, providing insights into CP violation and decay dynamics.

Contribution

It presents the first measurements of triple product asymmetries and polarization parameters in B_s^0 to phi phi decays at LHCb.

Findings

Measured polarization amplitudes and phase differences.

Observed triple product asymmetries consistent with Standard Model expectations.

Enhanced understanding of CP violation in B_s^0 decays.

Abstract

Using 1fb^{-1} of pp collision data collected at center of mass energy sqrt{s} = 7 TeV during 2011 by the LHCb detector. Measurements of the triple product asymmetries, polarisation amplitudes and strong phase difference in the decay B_s^0 to phi phi are presented.
