Symmetry Breaking and Axionic Strings in the Warped Deformed Conifold
نویسندگان
چکیده
We interpret D-strings at the bottom of the warped deformed conifold as axionic strings in the dual cascading SU(N + M) × SU(N) gauge theory. The axion is a massless pseudo-scalar glueball which we find in the supergravity fluctuation spectrum and interpret as the Goldstone boson of spontaneously broken U(1) baryon number symmetry. The existence of this massless glueball, anticipated in hep-th/0101013, supports the idea that the cascading gauge theory is on the baryonic branch, i.e. the U(1)B global symmetry is broken by expectation values of baryonic operators.

Supergravity and a Confining Gauge Theory: Duality Cascades and χSB–Resolution of Naked Singularities
We revisit the singular IIB supergravity solution describing M fractional 3branes on the conifold [hep-th/0002159]. Its 5-form flux decreases, which we explain by showing that the relevantN = 1 SUSY SU(N+M)×SU(N) gauge theory undergoes repeated Seiberg-duality transformations in which N → N −M . Far in the IR the gauge theory confines; its chiral symmetry breaking removes the singularity of hep...
متن کاملVariations on the Warped Deformed Conifold
The warped deformed conifold background of type IIB theory is dual to the cascading SU(M(p+1))×SU(Mp) gauge theory. We show that this background realizes the (super-)Goldstone mechanism where the U(1) baryon number symmetry is broken by expectation values of baryonic operators. The resulting massless pseudo-scalar and scalar glueballs are identified in the supergravity spectrum. A D-string is t...
متن کامل2 00 3 Remarks on the Warped Deformed Conifold ∗
We assemble a few remarks on the supergravity solution of hep-th/0007191, whose UV asymptotic form was previously found in hep-th/0002159. First, by normalizing the R-R fluxes, we compare the logarithmic flow of couplings in supergravity with that in field theory, and find exact agreement. We also write the 3-form field strength G3 = F3 − τH3 present in the solution in a manifestly SO(4) invari...
متن کاملDBI Global Strings
In this note we present global string solutions which are a generalization of the usual field theory global vortices when the kinetic term is DBI. Such vortices can result from the spontaneous symmetry breaking in the potential felt by a D3-brane. In a previous paper (hep-th/0706.0485), the DBI instanton solution was constructed which develops a ”wrinkle” for stringy heights of the potential. A...
متن کاملNon-Abelian (p,q) Strings in the Warped Deformed Conifold
We calculate the tension of (p, q)-strings in the warped deformed conifold using the non-Abelian DBI action. In the large flux limit, we find exact agreement with the recent expression obtained by Firouzjahi, Leblond and Henry-Tye up to and including order 1/M2 terms if q is also taken to be large. Furthermore using the finite q prescription for the symmetrised trace operation we anticipate the...
