Renormalization Group Analysis of Lattice Theories and Improved Lattice Action. II -- four-dimensional non-abelian SU(N) gauge model
read the original abstract
A new block spin renormalization group transformation for SU(N) gauge models is proposed near the non-trivial fixed point in perturbation theory and thereby the expectation values of various Wilson loops on the renormalized trajectory near the fixed point are explicitly obtained. An improved action is obtained as in a preceding paper and a criterion for the scaling behavior of physical quantities is also given.

Study on the systematic effects on $b \to c$ inclusive semileptonic decays
Lattice QCD study analyzes key systematics in inclusive B_s to X_c l nu decays and isolates excited-state contributions by treating ground states exclusively to reduce uncertainties.

Understanding the structure of nucleon excitations from their wavefunctions
Lattice calculations of nucleon wavefunctions reveal superposition nodes from mixing interpolating fields and built-in nodes intrinsic to individual s-wave Dirac components.

Ether of Orbifolds
Orbifold lattices incur m^4 Trotter overhead, m^2 contamination, and mandatory mass extrapolation, rendering them 10^4 to 10^10 times costlier than alternatives for a 10^3 calculation.
