Measurement of the branching fraction of the decay $J / I ¨ \to p p ˉ I^\cdot$

BESIII Collaboration, M. Ablikim, M. N. Achasov +645

A high precision measurement of the branching fraction of the decay $J / I ¨ \to p p ˉ I^\cdot$ is performed using $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events recorded by the {BESIII} d…

Cross section measurement of $e^{+} e^{-} \to I^\cdot I ¨ (2 S)$ and search for $e^{+} e^{-} \to I^\cdot X ~ (3872)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +645

The energy-dependent cross section for $e^{+} e^{-} \to I^\cdot I ¨ (2 S)$ is measured at eighteen center of mass energies from 4.288 GeV to 4.951 GeV using the BESIII detector. Using the same da…

Study of $D_{s}^{+} \to f_{0} (980) I ¨ ^{+}$ and $I ¨ I ¨ ^{+}$ decays through $D_{s}^{+} \to I ¨ ^{+} I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +655

We perform the first amplitude analysis of $D_{s}^{+} \to I ¨ ^{+} I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ decays, based on data samples of electron-positron collisions recorded with the BESIII detector at center-of…

Search for $I^\cdot_{c} (2 S) \to 2 (I ¨ ^{+} I ¨ ^{-})$ and improved measurement of $I ¨ _{c J} \to 2 (I ¨ ^{+} I ¨ ^{-})$

BESIII Collaboration, M. Ablikim, M. N. Achasov +643

We search for the hadronic decay $I^\cdot_{c} (2 S) \to 2 (I ¨ ^{+} I ¨ ^{-})$ in the $I ¨ (3686) \to I^^{3} I^\cdot_{c} (2 S)$ radiative decay using $(27.12 \pm 0.14) \times 1 0^{8}$ $I ¨ (3686)$ events collected by the BESI…
