TY - JOUR ID - 76402 AU - Lichard, Peter PY - 2023 TI - New narrow resonance in the e plus e - →<i> φη</i> data by the Belle collaboration JF - Physical Review D VL - 108 IS - 9 SP - "092005-1"-"092005-4" EP - "092005-1"-"092005-4" SN - 24700010 KW - Belle Collaboration KW - e+e-→φη;resonance;CMD-3 experiment UR - https://journals.aps.org/prd/abstract/10.1103/PhysRevD.108.092005 N2 - Fitting the recent e+e- -> phi eta data by the Belle Collaboration with a theoretical formula reveals, besides the dominant phi(1680) resonance, two narrow resonances: expected phi(2170) resonance and an unexpected resonance with the mass of about 1851 MeV. Close proximity to the X(1835) resonance suggests that the new resonance may be interpreted as the pp over bar baryonium in an excited state. Follow-up analysis found the same resonance also in e+e- -> omega eta data by the CMD-3 experiment. ER -
