Gauge theory and string theory represent two foundational pillars in contemporary theoretical physics, offering profound insights into the nature of fundamental interactions and the structure of the ...

We consider one-loop corrections 4 Δ a to inverse gauge couplings g a −2 in supersymmetric vacua of the heterotic string. The form of these corrections plays an important role in scenarios for ...

The field theory of free strings is analyzed in gauges in which the two-dimensional metric along the string worldsheet remains as a dynamical variable. Hamiltonian-based BRST methods are used. The ...
