Search for sub-GeV invisible particles in inclusive decays of to
BESIII Collaboration, M. Ablikim, M. N. Achasov +696
A search for an invisible particle, , with a mass between 0 and 0.96 , is performed in the process using $(8774.0\pm39.4)\times…

BESIII Collaboration, M. Ablikim, M. N. Achasov +650
Using collision data at 13 center-of-mass energies ranging from 4.600 to 4.950 GeV collected with the BESIII detector, we search for the unmeasured $e^+e^-\to K_S^0 K_S^0…
