Observation of $I ¨ (3686) \to I^^{-} K_{S}^{0} I^ˉ c ◯^{+}$ +c.c

BESIII Collaboration, M. Ablikim, M. N. Achasov +678

Using a sample of $(2.712 \pm 0.014) \times 1 0^{9}$ $I ¨ (3686)$ events collected with the BESIII detector at the electron positron collider BEPCII, the decay $Ï(3686) \to Î^- K^0_S…

Study of $I^\cdot \to I ¨ ^{+} I ¨ ^{-} l^{+} l^{-}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +639

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / I ¨ $ events accumulated with the BESIII detector, we analyze the decays $I^\cdot \to I ¨ ^{+} I ¨ ^{-} l^{+} l^{-}$ ( $l = e$ or $I^¼$ ) via the process…

An Enigmatic PeVatron in an Area around HII Region G35.6 $-$ 0.5

The LHAASO Collaboration, Zhen Cao, F. Aharonian +294

Identifying Galactic PeVatrons (PeV particle accelerators) from the ultra-high-energy (UHE, >100 TeV) $I^^{3}$ -ray sources plays a crucial role in revealing the origin of Galactic cosm…
