Mass corrections in string theory and lattice field theory
Kaluza-Klein compactifications of higher dimensional Yang–Mills theories contain a number of four dimensional scalars corresponding to the internal components of the gauge field. While at tree-level the scalar zero modes are massless, it is well known that quantum corrections make them massive. We compute these radiative corrections at 1–loop in an effective field theory framework, using the ba...
متن کاملString Threshold corrections from Field Theory
A field theory approach to summing threshold effects to the gauge couplings in a two-torus compactification is presented and the link with the (heterotic) string calculation is carefully investigated. We analyse whether the complete UV behaviour of the theory may be described on pure field theory grounds, as due to momentum modes only. “Non-decoupling” effects of a small dimension are discussed...
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...

15 صفحه اولString corrections to gauge couplings from a field theory approach
An effective field theory approach is introduced to compute one-loop radiative corrections to the gauge couplings due to Kaluza-Klein states associated with a two torus compactification. The results are compared with those of the string in the field theory " limit " α ′ → 0. The whole U and the leading T moduli dependence of the gauge dependent part of the string corrections to gauge couplings ...
