Localized tachyon condensation and G-parity conservation
نویسندگان
چکیده
We study the condensation of localized tachyon in non-supersymmetric orbifold. We first show that the G-parity of chiral primaries are preserved under the condensation of localized tachyon(CLT). Using this, we finalize the proof of the conjecture that the lowest-tachyon-mass-squared increases under CLT at the level of type II string with full consideration of GSO projection. We also show the equivalence between the G-parity given by G = [jk1/n] + [jk2/n] coming from partition function and that given by G = {jk1/n}k2 − {jk2/n}k1 coming from the monomial construction for the chiral primaires in the dual mirror picture.

We discuss the localized tachyon condensation in the non-supersymmetric orbifold theories by taking the cosmological constant as the measure of degrees of freedom. We show that both localized and delocalized degrees of freedom encode information on the process of localized tachyon condensation: the former encodes in the c-function given by the lightest tachyon mass, and the latter in the g-func...

We discuss the localized tachyon condensation in the non-supersymmetric orbifold theories by taking the cosmological constant as the measure of degrees of freedom (d.o.f). We first show asymptotic density of state is not a proper quantity to count the ’localized’ d.o.f. We then show that localized d.o.f lead us a c-function given by the lightest tachyon mass, which turns out to be the same as t...
متن کاملClosed String Tachyon Condensation: An Overview
These notes are an expanded version of a review lecture on closed string tachyon condensation at the RTN workshop in Copenhagen in September 2003. We begin with a lightning review of open string tachyon condensation, and then proceed to review recent results on localized closed string tachyon condensation, focusing on two simple systems, C/Zn orbifolds and twisted circle compactifications.
متن کاملLocalized tachyon mass and a g-theorem analogue
We study the localized tachyon condensation (LTC) of non-supersymmetric orbifold backgrounds in their mirror Landau-Ginzburg picture. Using he existence of four copies of (2,2) worldsheet supersymmetry, we show at the CFT level, that the minimal tachyon mass in twisted sectors shows somewhat analogous properties of cor g-function. Namely, m := |α′M2 min| satisfies m(M) ≥ m(D1 ⊕D2) = max{m(D1),m...
