Anomalous radius shift in AdS(4)/CFT(3)
Oren Bergman, Shinji Hirano
We study higher order corrections to the radius/M2-brane charge of AdS_4 x S^7/Z_k. There are two sources of corrections: one from the orbifold singularity of C^4/Z_k, and the othe…
Fractional M2-branes
Ofer Aharony, Oren Bergman, Daniel Louis Jafferis
We consider two generalizations of the N=6 superconformal Chern-Simons-matter theories with gauge group U(N)xU(N). The first generalization is to N=6 superconformal U(M)xU(N) theor…
N=6 superconformal Chern-Simons-matter theories, M2-branes and their gravity duals
Ofer Aharony, Oren Bergman, Daniel Louis Jafferis +1
We construct three dimensional Chern-Simons-matter theories with gauge groups U(N)xU(N) and SU(N)xSU(N) which have explicit N=6 superconformal symmetry. Using brane constructions w…
Quark mass and condensate in HQCD
Oren Bergman, Shigenori Seki, Jacob Sonnenschein
We extend the Sakai-Sugimoto holographic model of QCD (HQCD) by including the scalar bi-fundamental "tachyon" field in the 8-brane-anti-8-brane probe theory. We show that this fiel…
Semi-localized instability of the Kaluza-Klein linear dilaton vacuum
Oren Bergman, Shinji Hirano
The Kaluza-Klein linear dilaton background of the bosonic string and the Scherk-Schwarz linear dilaton background of the superstring are shown to be unstable to the decay of half o…
On the CSFT approach to localized closed string tachyons
Oren Bergman, Shlomo S. Razamat
We compute the potential for localized closed string tachyons in bosonic string theory on the orbifold C/Z_4 using level-truncated closed string field theory. The critical points o…
