Determination of the absolute branching fractions of and

BESIII Collaboration, M. Ablikim, M. N. Achasov +502

Using 2.93 fb of collision data collected with the BESIII detector at a center-of-mass energy of 3.773 GeV, we measure the absolute branching fractions of the decay…

Search for the decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +506

Using 6.32 fb of electron-positron collision data recorded by the BESIII detector at center-of-mass energies between 4.178 and 4.226~GeV, we present the first search for the…

Weather conditions several hours before the strong earthquake

Tao Chen, Lei Li, Xiao-Xin Zhang +3

Physical phenomena observed before strong earthquake have been reported over centuries. Radon anomalies, electrical signals, water level changes, earthquake lights near the epicent…

Hour-scale persistent negative anomaly of atmospheric electrostatic field near the epicenter before earthquake

Tao Chen, Han Wu, Chi Wang +28

Although earthquake prediction is a big challenge in the world, some simple observational tools can capture many physical signals and demonstrate that an earthquake (EQ) may be for…
