Metric-affine gauge theory of gravity: field equations, Noether identities, world spinors, and breaking of dilation invariance
In Einstein's gravitational theory, the spacetime is Riemannian, that is, it has vanishing
torsion and vanishing nonmetricity (covariant derivative of the metric). In the gauging of the …

Light pseudoscalars, particle physics and cosmology
JE Kim - Physics Reports, 1987 - Elsevier
We review physics of light pseudoscalars (axions, majorons and familons) and their effects
in cosmology. The axions which solve the strong CP problem play important roles in …

Gauge theory correlators from non-critical string theory
We suggest a means of obtaining certain Green's functions in 3+ 1-dimensional N= 4

The quartic effective action for the heterotic string
We calculate the complete low-energy effective action to quartic order in the bosonic fields
for the heterotic string. We find that, in addition to the term involving Ξ (3) found previously …
