Study of the $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} D_{s}^{+} D_{s}^{-}$ process from $s$ = 4.42 to 4.95 GeV at BESIII

BESIII Collaboration, M. Ablikim, M. N. Achasov +782

Based on $8.5 fb^{- 1}$ of $e^{+} e^{-}$ collision data collected at center-of-mass energies between 4.42 and 4.95 GeV with the BESIII detector at the BEPCII storage ring, we inves…

Constraining the Cosmic-ray Energy Based on Observations of Nearby Galaxy Clusters by LHAASO

The LHAASO Collaboration, Zhen Cao, F. Aharonian +323

Galaxy clusters act as reservoirs of high-energy cosmic rays (CRs). As CRs propagate through the intracluster medium, they generate diffuse $I^^{3}$ -rays detectable by arrays such as L…
