The authors' main claim Systematic uncertainty of gamma coming from the current limits on direct CP violation in D->K0Spi+pi- is estimated, and a modified model-independent procedure of B->DK, D->K0Spi+pi- Dalitz plot analysis is proposed that gives an unbiased gamma measurement even in presence of direct CP violation in charm decays.

The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; .

A possible effect of direct CP violation in D->K0Spipi decay on the gamma measurement from B->DK, D->K0Spi+pi- Dalitz plot analysis is considered. Systematic uncertainty of gamma coming from the current limits on direct CP violation in D->K0Spi+pi- is estimated, and a modified model-independent procedure of B->DK, D->K0Spi+pi- Dalitz plot analysis is proposed that gives an unbiased gamma measurement even in presence of direct CP violation in charm decays. The technique is applicable to other three-body D decays such as D->K0SK+K-, D->pi+pi-pi0, etc.

  • The types of measurements that dominate $γ$ sensitivity are based on decays where the neutral $D$ meson decays into a $CP$ eigenstate (commonly referred to as the GLW method [ref] ), suppressed $Kπ$ state (ADS method [ref] ), or self-conjugate three-body final state such as (GGSZ or Dalitz plot method [ref] ).
