One loop in $D = 11$ vs $D = 10$ : 4-point check

Aviral Aggarwal, Subhroneel Chakrabarti, Steven Weilong Hsia +2

The one-loop correction to eleven-dimensional supergravity involves a cubically divergent term $t_{8} t_{8} R^{4}$ , with four Riemann tensors. A similar term (with finite coefficient) has…

No manifest T-duality at order $I^\pm^{'3}$

Steven Weilong Hsia, Ahmed Rakin Kamal, Linus Wulff

When reduced from $10$ to $10 - d$ dimensions tree-level string theory exhibits an $O (d, d)$ symmetry. This symmetry, which is closely related to T-duality, appears only after certain…

Second order bosonic string effective action from $O (d, d)$

Linus Wulff

The corrections to the tree-level effective action for the bosonic string up to second order in $I^\pm^{'}$ are fixed by requiring its dimensional reduction to $26 - d$ dimensions to be co…

Tree-level $R^{4}$ correction from $O (d, d)$ : NS-NS five-point terms

Linus Wulff

The tree-level string effective action reduced from $D$ to $D - d$ dimensions possesses a continuous $O (d, d)$ symmetry, closely related to T-duality. A necessary condition for a high…
