Lambda_b-Polarization from its Inclusive Semileptonic Decay

J. G. K"orner

We discuss the Lambda_b-polarization of the bottom baryon Lambda_b in its production and in its decay. Standard Model predictions for b-quark polarization on the Z-peak are reviewe…

Errors in Monte Carlo simulations using shift register random number generators

F. Schmid, N. B. Wilding

We report large systematic errors in Monte Carlo simulations of the tricritical Blume-Capel model using single spin Metropolis updating. The error, manifest as a $20%$ asymmetry i…

Improved variables for measuring the $L amb d a_{b}$ polarization

C. Diaconu, J. G. Körner, D. Pirjol +1

We discuss a few possible strategies for measuring the polarization of the $Λ_{b}$ baryons produced in $e^{+} e^{-}$ -annihilation at the $Z$ resonance through their in…

Two-loop $O (N_{f} α_{s}^{2})$ correction to the decay width of the Higgs boson to two massive fermions

K. Melnikov

We present an analytical calculation of additional real or virtual radiation of the light fermion pair in the fermionic decay of the Higgs boson $H \to f_{1} f ˉ_{1}$ for arbitrary…

Ising Spins on a Gravitating Sphere

Christian Holm, Wolfhard Janke

We investigated numerically an Ising model coupled to two-dimensional Euclidean gravity with spherical topology, using Regge calculus with the $d l / l$ path-integral measure to discr…
