CPviolation for Electroweak Baryogenesis from Dynamical CKM Matrix
[DESY17094]
The CKM matrix can be the source of CPviolation for electroweak baryogenesis if Yukawa couplings vary at the same time as the Higgs is acquiring its vacuum expectation value, offering new avenues for electroweak baryogenesis. These ideas apply if the mechanism explaining the flavour structure of the Standard Model is connected to electroweak symmetry breaking. [...]

Testing perturbation theory on the N$_f$ = 0 static quark potential
[hepph/0109093; DESY01096]
ddc:530
The perturbative expansion of static force and potential is reanalyzed concerning its practical applicability. A well behaved perturbative prediction is given by the integration of the renormalization group equation for the coupling α qq ( μ =1/ r )=( C f ) −1 r 2 F ( r ). [...]

The $N_f = 0$ heavy quark potential from short to intermediate distances
[DESY01095; heplat/0108008]
ddc:530
We study the potential of a static quark–antiquark pair in the range 0.05 fm⩽ r ⩽0.8 fm, employing a sequence of lattices up to 64 4 . Lattice artifacts in potential and force are investigated theoretically as well as numerically and continuum quantities are obtained by extrapolation of the results at finite lattice spacing. [...]

Heavy quark effective theory at one loop order: An Explicit example
[DESY01111; SHEP0122; heplat/0108018]
ddc:530
We consider correlation functions containing the axial current of one light and one heavy quark in the static approximation as well as in full QCD, using the lattice regularization. Up to oneloop order of perturbation theory, we study the difference between the full and the effective theory in the continuum limit. [...]

Future measurements of deeply virtual Compton scattering at HERMES
[hepph/0108077; DESY01109]
ddc:530
Prospects for future measurements of Deeply Virtual Compton Scattering at HERMES are studied using different simple models for parameterizations of generalized parton distributions (GPDs). Measurements of the lepton charge and lepton beam helicity asymmetry will yield important input for theoretical models towards the future extraction of GPDs..

Bmeson light cone distribution amplitudes in the heavy quark limit
[hepph/0109181; DESY01135; HUPD0108; JUPD0191]
ddc:530
We investigate the Bmeson lightcone distribution amplitudes in the heavyquark limit which are relevant for the QCD factorization approach for the exclusive Bmeson decays. We derive exact relations between two and threeparticle distribution amplitudes from the QCD equations of motion and heavyquark symmetry constraint. [...]

We accomplish our efforts to obtain predictions for all fourfermion final states of e+ e annihilation and the corresponding bremsstrahlung reactions which are possible in the framework of the Standard Model. For this purpose we have developed a program EE4FGAMMA. [...]
