Vector Mesons and an Interpretation of Seiberg Duality
Zohar Komargodski
We interpret the dynamics of Supersymmetric QCD (SQCD) in terms of ideas familiar from the hadronic world. Some mysterious properties of the supersymmetric theory, such as the emer…
Comments on scaling limits of 4d N=2 theories
Davide Gaiotto, Nathan Seiberg, Yuji Tachikawa
We revisit the study of the maximally singular point in the Coulomb branch of 4d N=2 SU(N) gauge theory with N_f=2n flavors for N_f<2N. When n >= 2, we find that the low-energy phy…
Axions in the Landscape and String Theory
Michael Dine, Guido Festuccia, John Kehayias +1
While axions seem ubiquitous in critical string theories, whether they might survive in any string theoretic description of nature is a difficult question. With some mild assumptio…
Stringy KLT relations, global symmetries, and E_7(7) violation
Henriette Elvang, Michael Kiermaier
We study consequences of the Kawai-Lewellen-Tye (KLT) relations applied to tree amplitudes in toroidal compactifications of string theory to four dimensions. The closed string tree…
Massive type IIA string theory cannot be strongly coupled
Ofer Aharony, Daniel Jafferis, Alessandro Tomasiello +1
Understanding the strong coupling limit of massive type IIA string theory is a longstanding problem. We argue that perhaps this problem does not exist; namely, there may be no stro…
The Weinberg Operator and a Lower String Scale in Orientifold Compactifications
Mirjam Cvetič, James Halverson, Paul Langacker +1
We investigate the interplay between the string scale and phenomenological scales in orientifold compactifications. Specifically, we discuss in generality the tension that often ar…
