Maximal twist and the spectrum of quenched twisted mass lattice QCD

Abdou M. Abdel-Rehim, Randy Lewis, R. M. Woloshyn

Results on the hadron masses for a degenerate doublet of up and down quarks from quenched twisted mass lattice QCD at maximal twist are presented. Two definitions of maximal twist…

TaylUR, an arbitrary-order diagonal automatic differentiation package for Fortran 95

G. M. von Hippel

We present TaylUR, a Fortran 95 module to automatically compute the numerical values of a complex-valued function's derivatives w.r.t. several variables up to an arbitrary order in…

Automatically generating Feynman rules for improved lattice field theories

A. Hart, G. M. von Hippel, R. R. Horgan +1

Deriving the Feynman rules for lattice perturbation theory from actions and operators is complicated, especially when improvement terms are present. This physically important task…

The cone length and category of maps: pushouts, products and fibrations

Martin Arkowitz, Donald Stanley, Jeffrey Strom

For any collection of spaces A, we investigate two non-negative integer homotopy invariants of maps: l_A(f), the A-cone length of f, and L_A(f), the A-category of f. When A is the…

Equivariant cohomology of real flag manifolds

Augustin-Liviu Mare

Let $P = G / K$ be a semisimple non-compact Riemannian symmetric space, where $G = I_{0} (P)$ and $K = G_{p}$ is the stabilizer of $p \in P$ . Let $X$ be an orbit of the (isotropy) representation…
