The strength of the interaction between quarks and gluons
Mattia Dalla Brida, Roman Höllwieser, Francesco Knechtli +4
Modern particle physics experiments, e.g. at the Large Hadron Collider (LHC) at CERN, crucially depend on the precise description of the scattering processes in terms of the known…
A quenched study of m_b in HQET beyond the leading order
Michele Della Morte, Nicolas Garron, Rainer Sommer +1
A non perturbative method to compute the mass of the b quark including the 1/m term in HQET has been presented in a companion talk. Following this strategy, we find in the MS bar s…
String Breaking as a Mixing Phenomenon in the SU(2) Higgs Model
F. Knechtli, R. Sommer
We study the potential of a static quark anti-quark pair in the confinement ``phase'' of the SU(2) Higgs model. Around separation r_b, the confining string of the gauge field break…
String breaking in SU(2) gauge theory with scalar matter fields
Francesco Knechtli, Rainer Sommer
We investigate the static potential in the confinement phase of the SU(2) Higgs model on the lattice, where this model is expected to have properties similar to QCD. We observe tha…
