From Linear SUSY to Constrained Superfields
Zohar Komargodski, Nathan Seiberg
We present a new formalism for finding the low-energy effective Lagrangian of Goldstinos and other fields. This Lagrangian is written using standard superspace and the superfields…
27/32
Yuji Tachikawa, Brian Wecht
We show that when an N=2 SCFT flows to an N=1 SCFT via giving a mass to the adjoint chiral superfield in a vector multiplet with marginal coupling, the central charges a and c of t…
Webs of five-branes and N=2 superconformal field theories
Francesco Benini, Sergio Benvenuti, Yuji Tachikawa
We describe configurations of 5-branes and 7-branes which realize, when compactified on a circle, new isolated four-dimensional N=2 superconformal field theories recently construct…
Stability Walls in Heterotic Theories
Lara B. Anderson, James Gray, Andre Lukas +1
We study the sub-structure of the heterotic Kahler moduli space due to the presence of non-Abelian internal gauge fields from the perspective of the four-dimensional effective theo…
Six-dimensional D_N theory and four-dimensional SO-USp quivers
Yuji Tachikawa
We realize four-dimensional N=2 superconformal quiver gauge theories with alternating SO and USp gauge groups as compactifications of the six-dimensional D_N theory with defects. T…
Comments on the Fayet-Iliopoulos Term in Field Theory and Supergravity
Zohar Komargodski, Nathan Seiberg
A careful analysis of the Fayet-Iliopoulos (FI) model shows that its energy momentum tensor and supersymmetry current are not gauge invariant. Since the corresponding charges are g…
