An investigation of the pipi S-wave model for measurements of gamma with B->D(K0Spipi)K at LHCb
The importance of the amplitude-model uncertainty in measurements of gamma from B->D(KSpipi)K is discussed. The isobar and K-matrix parameterisations of the pipi S-wave are investigated and a 3 degree uncertainty on gamma is estimated if the K matrix is neglected and the less physical isobar desc...

| Sumario: | The importance of the amplitude-model uncertainty in measurements of gamma from B->D(KSpipi)K is discussed. The isobar and K-matrix parameterisations of the pipi S-wave are investigated and a 3 degree uncertainty on gamma is estimated if the K matrix is neglected and the less physical isobar description is used. |
