Wilson line approach to gravity in the high energy limit
S. Melville, S. G. Naculich, H. J. Schnitzer +1
We examine the high energy (Regge) limit of gravitational scattering using a Wilson line approach previously used in the context of non-Abelian gauge theories. Our aim is to clarif…
Elliptic models and M-theory
I. P. Ennes, C. Lozano, S. G. Naculich +1
We give a unified analysis of four-dimensional elliptic models with N=2 supersymmetry and a simple gauge group, and their relation to M-theory. Explicit calculations of the Seiberg…
Two antisymmetric hypermultiplets in N=2 SU(N) gauge theory: Seiberg-Witten curve and M-theory interpretation
I. Ennes, S. Naculich, H. Rhedin +1
The one-instanton contribution to the prepotential for N=2 supersymmetric gauge theories with classical groups exhibits a universality of form. We extrapolate the observed regulari…
One-instanton predictions of Seiberg-Witten curves for product groups
I. P. Ennes, S. G. Naculich, H. Rhedin +1
One-instanton predictions for the prepotential are obtained from the Seiberg-Witten curve for the Coulomb branch of N=2 supersymmetric gauge theory for the product group \prod_{n=1…
Superconformal Coset Equivalence from Level-Rank Duality
S. G. Naculich, H. J. Schnitzer
We construct a one-to-one map between the primary fields of the N=2 superconformal Kazama-Suzuki models G(m,n,k) and G(k,n,m) based on complex Grassmannian cosets, using level-rank…
Large-N Universality of the Two-Dimensional Yang-Mills String
M. Crescimanno, S. Naculich, H. J. Schnitzer
We exhibit the gauge-group independence (``universality'') of all normalized non-intersecting Wilson loop expectation values in the large N limit of two-dimensional Yang-Mills theo…
Fermions Destabilize Electroweak Strings
Stephen G. Naculich
Z-strings in the Weinberg-Salam model including fermions are unstable for all values of the parameters. The cause of this instability is the fermion vacuum energy in the Z-string b…
Two-dimensional Yang-Mills Theories Are String Theories
S. G. Naculich, H. A. Riggs, H. J. Schnitzer
We show that two-dimensional SO(N) and Sp(N) Yang-Mills theories without fermions can be interpreted as closed string theories. The terms in the 1/N expansion of the partition func…
Third Generation Effects on Fermion Mass Predictions in Supersymmetric Grand Unified Theories
Stephen G. Naculich
Relations among fermion masses and mixing angles at the scale of grand unification are modified at lower energies by renormalization group running induced by gauge and Yukawa coupl…
Quantum Kinks: Solitons at Strong Coupling
Stephen G. Naculich
We examine solitons in theories with heavy fermions. These ``quantum'' solitons differ dramatically from semi-classical (perturbative) solitons because fermion loop effects are imp…
Can the Electroweak Symmetry-breaking Sector Be Hidden?
S. G. Naculich, C. -P. Yuan
In a recent paper, Chivukula and Golden claimed that the electroweak symmetry--breaking sector could be hidden if there were many inelastic channels in the longitudinal scatte…
Inelastic Channels in the Electroweak Symmetry-Breaking Sector
S. G. Naculich, C. -P. Yuan
It has been argued that if light Higgs bosons do not exist then the self--interactions of 's become strong in the TeV region and can be observed in longitudinal scattering.…
