Measurement of the branching fractions of Ds+→η′X and Ds+→η′ρ+ in e+e−→Ds+Ds−

М. Н. Ачасов, X. Ai, O. Albayrak, M. Albrecht et autres

We study D s + decays to final states involving the η ′ with a 482 pb − 1 data sample collected at s = 4.009 GeV with the BESIII detector at the BEPCII collider. We measure the branching fractions B ( …

Measurement of y CP in D 0 – D ¯ 0 oscillation using quantum correlations in e + e − → D 0 D ¯ 0 at s = 3.773 GeV

M. N. Achasov, X. Ai, O. Albayrak, M. Albrecht et autres

We report a measurement of the parameter y CP in D 0 – D ¯ 0 oscillations performed by taking advantage of quantum coherence between pairs of D 0 D ¯ 0 mesons produced in e + e − annihilations near threshold. …
