Measurement of the Inclusive Cross Sections of Prompt $J / I ¨ $ and $I ¨ (3686)$ Production in $e^{+} e^{-}$ Annihilation from $s = 3.808$ to $4.951$ GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +610

The inclusive cross sections of prompt $J / I ¨ $ and $I ¨ (3686)$ production are measured at center-of-mass energies from 3.808 to 4.951 GeV. The dataset used is 22 fb $^{- 1}$ of $e^{+}e…

Observation of $I^\cdot_{c}$ (1S, 2S) and $I ¨ _{c J}$ decays to 2 $(I ¨ ^{+} I ¨ ^{-}) I^\cdot$ via $I ¨ $ (3686) radiative transitions

BESIII Collaboration, M. Ablikim, M. N. Achasov +642

Based on $2.7 \times 1 0^{9} I ¨ (3686)$ decays collected with the BESIII detector, the radiative decay $I ¨ (3686) \to γ 2 (I ¨ ^{+} I ¨ ^{-}) I^\cdot$ is investigated to measure properties of S-…

Soft X-ray prompt emission from a high-redshift gamma-ray burst EP240315a

Y. Liu, H. Sun, D. Xu +191

Long gamma-ray bursts (GRBs) are believed to originate from core collapse of massive stars. High-redshift GRBs can probe the star formation and reionization history of the early un…

Observation of the Anomalous Shape of $X (1840)$ in $J / I ¨ \to I^^{3} 3 (I ¨ ^{+} I ¨ ^{-})$ Indicating a Second Resonance Near $p p ˉ$ Threshold

BESIII Collaboration, M. Ablikim, M. N. Achasov +615

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events, which is about 45 times larger than that was previously analyzed, a further investigation on the $J/Ï\rightarrow Î³3(Ï^…
