F-theory and linear sigma models

M. Bershadsky, T. M. Chiang, B. R. Greene +2

We present an explicit method for translating between the linear sigma model and the spectral cover description of SU(r) stable bundles over an elliptically fibered Calabi-Yau mani…

D-Brane Topology Changing Transitions

Brian R. Greene

We study D-branes on three-dimensional orbifold backgrounds that admit topologically distinct resolutions differing by flop transitions. We show that these distinct phases are part…

An Approximate Large $N$ Method for Lattice Chiral Models

Stuart Samuel

An approximation is used that permits one to explicitly solve the two-point Schwinger-Dyson equations of the U(N) lattice chiral models. The approximate solution correctly predicts…

Two Massive and One Massless Sp(4) Monopoles

Kimyeong Lee, Changhai Lu

Starting from Nahm's equations, we explore BPS magnetic monopoles in the Yang-Mills Higgs theory of gauge group $S p (4)$ which is broken to $S U (2) \times U (1)$ . A family of BPS field…

Calogero-Moser Systems in SU(N) Seiberg-Witten Theory

Eric D'Hoker, D. H. Phong

The Seiberg-Witten curve and differential for $N = 2$ supersymmetric SU(N) gauge theory, with a massive hypermultiplet in the adjoint representation of the gauge group, are an…

Dynamics of BPS Dyons: Effective Field Theory Approach

Dongsu Bak, Choonkyu Lee, Kimyeong Lee

Based on a detailed analysis of nonlinear field equations of the SU(2) Yang-Mills-Higgs system, we obtain the effective field theory describing low-energy interaction of BPS dyons…

Four-dimensional BPS-spectra via M-theory

Mans Henningson, Piljin Yi

We consider the realization of four-dimensional theories with N = 2 supersymmetry as M-theory configurations including a five-brane. Our emphasis is on the spectrum of massive stat…

A Family of N=2 Gauge Theories with Exact S-Duality

Kimyeong Lee, Piljin Yi

We study an infinite family of N=2 $S p (2 n)$ gauge theories that naturally arise from the D3-brane probe dynamics in F-theory. The matter sector consists of four fundamental and one…

Solutions of Extended Supersymmetric Matrix Models for Arbitrary Gauge Groups

Stuart Samuel

Energy eigenstates for N=2 supersymmetric gauged quantum mechanics are found for the gauges groups SU(n) and U(n). The analysis is aided by the existence of an infinite number of c…

Pre-Big-Bang Inflation Requires Fine Tuning

Michael S. Turner, Erick J. Weinberg

The pre-big-bang cosmology inspired by superstring theories has been suggested as an alternative to slow-roll inflation. We analyze, in both the Jordan and Einstein frames, the eff…

Orbifold Resolution by D-Branes

Michael R. Douglas, Brian R. Greene, David R. Morrison

We study topological properties of the D-brane resolution of three-dimensional orbifold singularities, C^3/Gamma, for finite abelian groups Gamma. The D-brane vacuum moduli space i…

Witten Index and Threshold Bound States of D-Branes

Piljin Yi

We consider the Witten index $I = T r (- 1)^{F}$ of SU(2) Super-Yang-Mills quantum mechanics (SYMQ) with N=16, 8, 4 supersymmetries. The theory governs the interactions between a…

Elliptic solutions to difference non-linear equations and related many-body problems

I. Krichever, P. Wiegmann, A. Zabrodin

We study algebro-geometric (finite-gap) and elliptic solutions of fully discretized KP or 2D Toda equations. In bilinear form they are Hirota's difference equation for $τ$ -function…

Solitons in high-energy QCD

G. P. Korchemsky, I. M. Krichever

We study the asymptotic solutions of the Schrödinger equation for the color-singlet reggeon compound states in multi-color QCD. We show that in the leading order of asymptotic expa…

Vector Bundles And F Theory

Robert Friedman, John Morgan, Edward Witten

To understand in detail duality between heterotic string and F theory compactifications, it is important to understand the construction of holomorphic G bundles over elliptic Calab…

Monopoles and Instantons on Partially Compactified D-Branes

Kimyeong Lee, Piljin Yi

Motivated by the recent D-brane constructions of world-volume monopoles and instantons, we study the supersymmetric SU(N) Yang-Mills theory on $S^{1} \times R^{3 + 1}$ , spontaneously b…

Some Features of (0,2) Moduli Space

Ti-Ming Chiang, Jacques Distler, Brian R. Greene

We discuss some aspects of perturbative $(0, 2)$ Calabi-Yau moduli space. In particular, we show how models with different $(0, 2)$ data can meet along various sub-loci in their modu…
