Chiral corrections to kaon-nucleon scattering lengths

We calculate the threshold T-matrices of kaon-nucleon and antikaon-nucleon scattering to one loop order in SU(3) heavy baryon chiral perturbation theory. To that order the complex-valued isospin-1 KN threshold T-matrix can be successfully predicted from the isospin-0 and 1 KN threshold T-matrices. As expected perturbation theory fails to explain the isospin-0 KN threshold T-matrix which is comp...

Fast n-point correlation functions and three-point lensing application

We present a new algorithm to rapidly compute the two-point (2PCF), three-point (3PCF) and n-point (n-PCF) correlation functions in roughly O(N) time for N particles, instead of O(Nn) as required by brute force approaches. This technique exploits node-to-node correlations of a recursive bisectional binary tree. A balanced tree construction minimizes the depth of the tree and the worst case erro...

Chiral Symmetry and the Nucleon Structure Functions

The flavor asymmetry of the sea quark distribution as well as the unexpectedly small quark spin fraction of the nucleon are two outstanding discoveries recently made in the physics of deep-inelastic structure functions. We evaluate here the corresponding quark distribution functions within the framework of the chiral quark soliton model, which is an effective quark model of baryons maximally in...

Two-point Functions at Two Loops in Three Flavour Chiral Perturbation Theory†

The vector and axial-vector two-point functions are calculated to nextto-next-to-leading order in Chiral Perturbation Theory for three light flavours. We also obtain expressions at the same order for the masses, mπ, m 2 K and mη, and the decay constants, Fπ, FK and Fη . We present some numerical results after a simple resonance estimate of some of the new O(p6) constants. PACS: 12.39.F, 14.40.A...
