摘要: Abstract The β functions are calculated for values of the momenta external legs in region masses particles internal loops. effects these an SU(2) × U(1) model weak and electromagnetic interactions a grand unified strong, discussed. most significant effect is reduction mass superheavy gauge bosons theories by factor 6, which decreases estimated proton lifetime three orders magnitude.
