The String Tension in Two Dimensional Gauge Theories
نویسنده
چکیده
We review and elaborate on properties of the string tension in two-dimensional gauge theories. The first model we consider is massive QED in the m ≪ e limit. We evaluate the leading string tension both in the fermionic and bosonized descriptions. We discuss the next to leading corrections in m/e. The next-to-leading terms in the long distance behavior of the quark-antiquark potential, are evaluated in a certain region of external versus dynamical charges. The finite temperature behavior is also determined. In QCD2 we review the results for the string tension of quarks in cases with dynamical quarks in the fundamental, adjoint, symmetric and antisymmetric representations. The screening nature of SY M2 is re-derived.

The k = 2 string tension in four dimensional SU ( N ) gauge theories
We calculate the k = 2 string tension in SU(4) and SU(5) gauge theories in 3+1 dimensions, and compare it to the k = 1 fundamental string tension. We find, from the continuum extrapolation of our lattice calculations, that σ k =2 /σ f = 1.40 ± 0.08 in the SU(4) gauge theory, and that σ k =2 /σ f = 1.56±0.10 in SU(5). We remark upon the way this might constrain the dynamics of confinement and th...
متن کاملScreening in Supersymmetric Gauge Theories in Two Dimensions
We show that the string tension in N = 1 two-dimensional super Yang-Mills theory vanishes independently of the representation of the quark anti-quark external source. We argue that this result persists in SQCD2 and in two-dimensional gauge theories with extended supersymmetry or in chiral invariant models with at least one massless dynamical fermion. We also compute the string tension for the m...
متن کاملString Tensions and Three Dimensional Confining Gauge Theories
In the context of gauge/gravity duality, we try to understand better the proposed duality between the fractional D2-brane supergravity solutions of (Nucl. Phys. B 606 (2001) 18, hep-th/0101096) and a confining 2+ 1 dimensional gauge theory. Based on the similarities between this fractional D2-brane solution and D3-brane supergravity solutions with more firmly established gauge theory duals, we ...
متن کاملSuperYang-Mills,MatrixModels andGeometric Transitions SuperYang-Mills, modèles dematrices et transitions géométriques
I explain two applications of the relationship between four dimensional N = 1 supersymmetric gauge theories, zero dimensional gauged matrix models, and geometric transitions in string theory. The first is related to the spectrum of BPS domain walls or BPS branes. It is shown that one can smoothly interpolate between a D-brane state, whose weak coupling tension scales as N ∼ 1/gs, and a closed s...
متن کاملNoncommutative Sp(2,R) Gauge Theories A Field Theory Approach to Two-Time Physics
Phase-space and its relativistic extension is a natural space for realizing Sp(2,R) symmetry through canonical transformations. On a D×2 dimensional covariant phase-space, we formulate noncommutative field theories, where Sp(2,R) plays a role as either a global or a gauge symmetry group. In both cases these field theories have potential applications, including certain aspects of string theories...
