Bosonic color-flavor transformation for the special unitary group
نویسندگان
چکیده
We extend Zirnbauer’s color-flavor transformation in the bosonic sector to the color group SU(Nc). Because the flavor group U(Nb, Nb) is non-compact, the algebraic method by which the original color-flavor transformation was derived leads to a useful result only for 2Nb ≤ Nc. Using the character expansion method, we obtain a different form of the transformation in the extended range Nb ≤ Nc. This result can also be used for the color group U(Nc). The integrals to which the transformation can be applied are of relevance for the recently proposed boson-induced lattice gauge theory.

Color-Flavor Transformation for the Special Unitary Group and Application to Low Energy QCD
The color-flavor transformation for the unitary group (Zirnbauer 1996) is extended to the special unitary group. The resulting partition function is represented as sum over disconnected sectors characterized by a U(1)-charge. Application to low energy QCD on a lattice leads to a theory where the inverse number of colors appears as expansion parameter. We use a saddle point approximation to esti...
متن کاملBehavior of $R$-groups for $p$-adic inner forms of quasi-split special unitary groups
We study $R$-groups for $p$-adic inner forms of quasi-split special unitary groups. We prove Arthur's conjecture, the isomorphism between the Knapp-Stein $R$-group and the Langlands-Arthur $R$-group, for quasi-split special unitary groups and their inner forms. Furthermore, we investigate the invariance of the Knapp-Stein $R$-group within $L$-packets and between inner forms. This w...
متن کاملUltracoherence and Canonical Transformations
Canonical transformations are studied in the bosonic Fock space using coherent and ultracoherent vectors. The connection between the Weyl operator and the homogeneous canonical transformations (Bogoliubov transformations) is presented. The unitary ray representation of the symplectic group is defined in the bosonic Fock space by the action of the group on the ultracoherent vectors.
متن کاملOn the SU (1, 1) Thermal Group of Bosonic Strings and D-Branes
All possible Bogoliubov operators that generate the thermal transformations in Thermo Field Dynamics (TFD) form a SU (1, 1) group. We discuss this construction in the bosonic string theory. In particular, the transformation of the Fock space and string operators generated by the most general SU(1, 1) unitary Bogoliubov transformation and the entropy of the corresponding thermal string are compu...
متن کاملAxions: Past, Present, and Future
Consider quantum chromodynamics (QCD) with color group SU(3) and three flavors of massless quarks. The lagrangian is invariant under an additional global flavor group, U(3)L × U(3)R. Although we will use it anyway, this “left–right” terminology is actually somewhat misleading; in four dimensions, a right-handed fermion field is the hermitian conjugate of a left-handed fermion field, and so we c...
