LHAASO Detection of Ultra-High-Energy Gamma-Ray Emission toward the Giant Molecular Clouds

Zhen Cao, F. Aharonian, Y. X. Bai +310

The $γ$ -ray from Giant molecular clouds (GMCs) is regarded as the most ideal tool to perform in-situ measurement of cosmic ray (CR) density and spectra in our Galaxy. We report the…

Energy calibration of LHAASO-KM2A using the cosmic ray Moon shadow

Zhen Cao, F. Aharonian, Y. X. Bai +323

We present a precise measurement of the westward, rigidity-dependent shift of the Moon's shadow using three and a half years of cosmic-ray data collected by the Kilometer Square Ar…

All-sky search for individual Primordial Black Hole bursts with LHAASO

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

Primordial Black Holes~(PBHs) are hypothetical black holes with a wide range of masses that formed in the early universe. As a result, they may play an important cosmological role…

Measurement of the branching fraction of leptonic decay $D_{s}^{+} \to τ^{+} ν_{τ}$ via $τ^{+} \to π^{+} π^{0} ν ˉ_{τ}$

M. Ablikim, M. N. Achasov, P. Adlarson +503

By analyzing $6.32 fb^{- 1}$ of $e^{+} e^{-}$ annihilation data collected at the center-of-mass energies between 4.178 and 4.226\,GeV with the BESIII detector, we determine the…

Measurements of the branching fractions of $ψ (3686) \to Σ ˉ^{0} Λ + c . c .$ and $χ_{c J (J = 0, 1, 2)} \to Λ Λ ˉ$

BESIII Collaboration, M. Ablikim, M. N. Achasov +505

Based on $4.481 \times 1 0^{8}$ $ψ (3686)$ events collected with the BESIII detector at BEPCII, the branching fraction of the isospin violating decay $ψ (3686) \to Σ ˉ^{0} Λ + c . c .$ …
