Measurement of Born cross sections for $e^{+} e^{-} \to p p ˉ$ at $s = 3.510 - 4.946$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +758

We report a measurement of the Born cross section and the effective form factor for the $e^{+} e^{-} \to p p ˉ$ reaction at 47 center-of-mass energies between 3.510 and 4.946 GeV. The…

Observation of $I ¨ (3770) \to p p ˉ$ and Measurement of Electromagnetic Form Factors of Proton at $s = 3.510 - 4.946$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +758

We search for possible charmonium(-like) states decaying into the $p p ˉ$ final state by studying the Born cross sections of the $e^{+} e^{-} \to p p ˉ$ reaction, and we determine…

Search for the charged lepton flavor violating decay $I^\cdot \to e^{\pm} I^¼^{\mp}$

M. Ablikim, M. N. Achasov, P. Adlarson +708

Based on $(10.087 \pm 0.044) \times 1 0^{9} J / I ¨ $ events collected at the center-of-mass energy $s = 3.097$ ~GeV with the BESIII detector, we search for the charged lepton fla…

Test of the JUNO 20-inch PMTs during Installation

Haojie Dong, Zhaoyuan Peng, Zhonghua Qin +13

Photomultiplier tubes (PMTs) are widely used in neutrino experiments. As a new-generation neutrino observatory, JUNO requires an excellent energy resolution of 3% at 1 MeV. This wi…
