A high-statistics sample of photoproduced charm from the FOCUS experiment has been used to search for direct CP violation in the decay rates for [Formula presented] and [Formula presented]. We have measured the following asymmetry parameters relative to [Formula presented]: [Formula presented], [Formula presented], and [Formula presented] relative to [Formula presented]. We have also measured the relative branching ratios and found [Formula presented], [Formula presented], and [Formula presented]. © 2002 The American Physical Society.

Abstract
A high-statistics sample of photoproduced charm from the FOCUS experiment has been used to search for direct CP violation in the decay rates for [Formula presented] and [Formula presented]. We have measured the following asymmetry parameters relative to [Formula presented]: [Formula presented], [Formula presented], and [Formula presented] relative to [Formula presented]. We have also measured the relative branching ratios and found [Formula presented], [Formula presented], and [Formula presented]. © 2002 The American Physical Society.File in questo prodotto:
