The BESIII collaboration have reported the observation of an anomalous line shape around ppbar mass threshold in the J/ψ→γ3(π+π-) decay, which indicates the existence of a ppbar bound state. The paper was published online in Physical Review Letters....

Efficiency boost: Dual light pulses minimize energy for phase transitions

Researchers have explained the mechanisms behind a counterintuitive phenomenon: Making a phase transition effective requires less energy if it is initiated by two pulses of light instead of just one. The energy needed to complete the phase transition has been reduced by 6% and could be further...

ATLAS provides first measurement of the W-boson width at the LHC
