Upper Bound of Proton Life-Time in Product-Group Unification
Models of supersymmetric grand unified theories based on SU(5)GUT×U(N)H gauge group (N = 2, 3) have a symmetry that guarantees light two Higgs doublets and absence of dimension-five proton decay operators. We analysed the proton decay induced by gauge-boson exchange in the models. Upper bounds of proton life-time are obtained; τ(p → πe)∼ 6.0×1033 yrs. in the SU(5)GUT×U(2)H model and τ(p → πe)∼ ...

متن کاملAn Upper Bound Analysis of Sandwich Sheet Rolling Process
In this research, flat rolling process of bonded sandwich sheets is investigated by the method of upper bound. A kinematically admissible velocity field is developed for a single layer sheet and is extended into the rolling of the symmetrical sandwich sheets. The internal, shear and frictional power terms are derived and they are used in the upper bound model. Through the analysis, the rolling ...
متن کاملAn Upper Bound on the First Zagreb Index in Trees
In this paper we give sharp upper bounds on the Zagreb indices and characterize all trees achieving equality in these bounds. Also, we give lower bound on first Zagreb coindex of trees.
