Holographic Consequences of Heterotic String Theory beyond its Supergravity Approximation

Leon Berdichevsky Acosta, Salman Sajad Wani, Arshid Shabir +6

In this work, we study the effects of stringy corrections on the low energy effective action derived from heterotic string theory beyond its supergravity approximation. Compactifyi…
