Tachyon-massless couplings at order in bosonic string theory
Mohammad R. Garousi
Recently, it has been proposed that the classical effective action of bosonic string theory should contain only couplings with an even number of tachyon fields. We employ the T-dua…
Tachyon couplings from S-matrix elements in bosonic string theory
Mohammad R. Garousi
We introduce a systematic framework for constructing spacetime and D-brane effective actions in bosonic string theory, encompassing both tachyon and massless modes. The actions are…
Heterotic string couplings at order in NS-NS sector
Alireza Pahlavan, Mehdi Ameri, Mohammad R. Garousi
We utilize the standard T-duality procedure to derive the classical effective action of heterotic string theory at the eight-derivative order within the NS-NS sector, which compris…
The emergence of inherently 9-dimensional one-loop effective action from T-duality
Mohammad R. Garousi
Recent studies suggest that applying the Buscher rules to the dimensional reduction of ten-dimensional, one-loop effective actions generate "purely stringy" couplings in nine dimen…
Dimensional reduction of the M-theory Chern-Simons term at order
Mohammad R. Garousi
The dimensional reduction of M-theory couplings at order is known to produce one-loop corrections in type IIA string theory. In this paper, we perform the Kaluza-…
Type IIA supergravity at one loop: terms in the metric-dilaton-RR one-form sector
Mohammad R. Garousi
The circle compactification of M-theory is dual to type IIA string theory, requiring that the dimensional reduction of the M-theory couplings \((t_8 t_8 - \frac{1}{4} ε_8 ε_8) R^4\…
