N. S. Mankoc Borstnik, C. D. Froggatt, D. Lukman +15
The present volume is the collection of contributions by friends of Holger Bech Nielsen for his 60th birthday. Contents: 1.Unified internal space of spins and charges (N. Mankoc Bo…
Weak form factors for heavy meson decays
Dmitri Melikhov, Berthold Stech
We calculate the form factors for weak decays of and mesons to light pseudoscalar and vector mesons within a relativistic dispersion approach based on the const…
Are the neutrino masses and mixings closely related to the masses and mixings of quarks?
B. Stech
The mass matrices of quarks have a simple structure if expressed in powers of the small parameter σ=(m_c/m_t)^{1/2}. If there is a close relation between quarks and leptons, one wo…
Hints from the Standard Model for Particle Masses and Mixings
Berthold Stech
The standard model taken with a momentum space cut-off may be viewed as an effective low energy theory. The structure of it and its known parameters can give us hints for relations…
A Form Factor Model for Exclusive B- and D-Decays
Berthold Stech
An explicit model is presented which gives the momentum transfer-dependent ratios of form factors of hadronic currents. For the unknown Isgur-Wise function and its generalization f…
