Query: On Standard Model Higgs and Superstring Theories   It is shown that in the Standard Model, the property of charge quantization
holds for a Higgs with arbitrary isospin and hypercharge. These defining
quantum numbers of the Higgs remain unconstrained while the whole basic and
fundamental structure of the Standard Model remains intact. Hence it is shown
that the Higgs cannot be a physical particle. Higgs is the underlying `vacuum'
over which the whole edifice of the Standard Model stands. Also on most general
grounds it is established here that as per the Standard Model there is no
electric charge above the electro-weak phase transition temperature. Hence
there was no electric charge present in the Early Universe. The Superstring
Theories are flawed in as much as they are incompatible with this requirement.
