We have searched for KS → 3π0 decay in a sample of ∼450 pb−1 of electron- positron collisions collected at the Frascati φ-factory DAΦNE. A direct ob- servation of this decay is a sign of CP violation and a stringent limit on its branching ratio, BR, helps on improving the accuracy on the CPT violation parameter of the mixing matrix δ. The most stringent limit on BR(KS → 3π0) is obtained.

Abstract
We have searched for KS → 3π0 decay in a sample of ∼450 pb−1 of electron- positron collisions collected at the Frascati φ-factory DAΦNE. A direct ob- servation of this decay is a sign of CP violation and a stringent limit on its branching ratio, BR, helps on improving the accuracy on the CPT violation parameter of the mixing matrix δ. The most stringent limit on BR(KS → 3π0) is obtained.File in questo prodotto:
