Measurement of the Cross Section for the Process e(+)e(-) -> omega pi(0) -> pi(+)pi(-)pi(0)pi(0) with the SND Detector

摘要

The process e(+)e(-) -> omega pi(0) -> pi(+)pi(-)pi(0)pi(0) was studied in the energy range between 1 and 2 GeV to the best precision in the world. The data used correspond to an integrated luminosity of 35 pb(-1) accumulated with the SND detector at the VEPP-2000 e(+)e(-) collider. The statistical accuracy of the measured cross section is 2 to 22%, whereas the systematic uncertainty is 2.6 to 14%. The present results agree with the results of earlier measurements but have a better precision.
