Study of the and Scalar Mesons through the Decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +605
Using collision data corresponding to an integrated luminosity of 7.33~ recorded by the BESIII detector at center-of-mass energies between 4.128 and 4.226~$…
An Ultrahigh-energy -ray Bubble Powered by a Super PeVatron
The LHAASO Collaboration, Z. Cao, F. Aharonian +277
We report the detection of a -ray bubble spanning at least 100 in ultra high energy (UHE) up to a few PeV in the direction of the star-forming region Cygnus X, imply…
Constraints on heavy decaying dark matter from 570 days of LHAASO observations
The LHAASO Collaboration, Zhen Cao, F. Aharonian +276
The Kilometer Square Array~(KM2A) of the Large High Altitude Air Shower Observatory (LHAASO) aims at surveying the northern gamma-ray sky at energies above 10 TeV with unprecedente…
Discovery of the Ultra-high energy gamma-ray source LHAASO J2108+5157
The LHAASO collaboration, Zhen Cao, F. Aharonian +267
We report the discovery of a UHE gamma-ray source, LHAASO J2108+5157, by analyzing the LHAASO-KM2A data of 308.33 live days. Significant excess of gamma-ray induced showers is obse…
Measurement of the branching fraction of the decay
BESIII Collaboration, M. Ablikim, M. N. Achasov +645
A high precision measurement of the branching fraction of the decay is performed using events recorded by the {BESIII} d…
Observation and branching fraction measurement of the decay
M. Ablikim, M. N. Achasov, P. Adlarson +612
