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…

Detection of two TeV gamma-ray outbursts from NGC 1275 by LHAASO

Zhen Cao, F. Aharonian, Axikegu +275

The Water Cherenkov Detector Array (WCDA) is one of the components of Large High Altitude Air Shower Observatory (LHAASO) and can monitor any sources over two-thirds of the sky for…

Broadband $I^^{3}$ -ray spectrum of supernova remnant Cassiopeia A

Zhen Cao, F. Aharonian, Y. X. Bai +311

The core-collapse supernova remnant (SNR) Cassiopeia A (Cas A) is one of the brightest galactic radio sources with an angular radius of $\sim$ 2.5 $\arcmin$. Although no extension…

Measurements of the branching fractions of semileptonic $D_{s}^{+}$ decays via $e^{+} e^{-} \to D_{s}^{+} D_{s}^{-}$

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

We measure the absolute branching fractions of semileptonic $D_{s}^{+}$ decays via the $e^{+} e^{-} \to D_{s}^{*+} D_{s}^{*-}$ process using $e^{+} e^{-}$ collision data corresponding to an integrated…

Test of lepton universality and measurement of the form factors of $D^{0} \to K^{*} (892)^{-} I^¼^{+} I^½_{I^} ¼$

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

We report a first study of the semileptonic decay $D^{0} \to K^{-} I ¨ ^{0} I^¼^{+} I^½_{I^} ¼$ by analyzing an $e^{+} e^{-}$ annihilation data sample of $7.9 fb^{- 1}$ collected at the c…
