On Link Invariants and Topological String Amplitudes
We explicitly show that the new polynomial invariants for knots, upto nine crossings, agree with the Ooguri-Vafa conjecture relating Chern-Simons gauge theory to topological string theory on the resolution of the conifold. From the multi-component link invariants in SU(N) Chern-Simons theory, we suggest a form for the new polynomial invariants. Email: [email protected] Email: [email protected]...
متن کاملGlobal Properties of Topological String Amplitudes and Orbifold Invariants
We derive topological string amplitudes on local Calabi-Yau manifolds in terms of polynomials in finitely many generators of special functions. These objects are defined globally in the moduli space and lead to a description of mirror symmetry at any point in the moduli space. Holomorphic ambiguities of the anomaly equations are fixed by global information obtained from boundary conditions at f...
متن کاملOne - Loop Amplitudes for e + e − → q̄qQ̄Q
We present the one-loop helicity amplitudes for processes involving a vector boson V (V = W, Z, or γ *) and four massless quarks, 0 → V ¯ qq ¯ QQ, where V couples to a massless lepton pair. These amplitudes are required for next-to-leading order O(α 3 s) numerical programs for four-jet production at e + e − colliders, for W , Z or Drell-Yan production in association with two jets at hadron coll...
متن کاملSuperconformal Invariants or How to Relate Four - point AdS Amplitudes
Using the form of N = 2 superconformal invariants we derive the explicit relation between the bottom and top components of the correlator of four stress-tensor multiplets in N = 4 Super Yang-Mills. The result is given in terms of an eighth order differential operator acting on the function of two variables which characterises these correlators. It allows us to show a non-trivial consistency rel...
متن کاملOne-Loop Amplitudes for e+ e− to Four Partons
We present the first explicit formulæ for the complete set of one-loop helicity amplitudes necessary for computing next-to-leading order corrections for e e annihilation into four jets, for W , Z or Drell-Yan production in association with two jets at hadron colliders, and for three-jet production in deeply inelastic scattering experiments. We include a simpler form of the previously published ...
