N S Mankoc Borstnik born in Buenos Aires in Argentina to Slovenian parents, she did her Ph.D. in physics 1974, University of Ljubljana. In 1975 she worked as an Assistant Professor, 1981 as an Associate Professor, 1986 (Full) Professor in Department of Physics of University of Ljubljana. In 1996 she was a Professor with a special status (with maximal number of points), University of Ljubljana, Department of Physics and from 1999-2004 she was a Founder and director of the Primorska Institute for Natural Sciences and Technology, Koper, Slovenia.
How far has so far the Spin-Charge-Family theory succeeded to explain the Standard Model assumptions, the matter-antimatter asymmetry, the appearance of the Dark Matter, making several predictions. More than 40 years ago the standard model made a successful new step in understanding properties of fermion and boson fields. Now the next step is needed, which would explain what the standard model and the cosmological models just assume:
a) The origin of quantum numbers of massless one family members.
b) The origin of families.
c) The origin of the vector gauge fields.
d) The origin of the Higgses and Yukawa couplings.
e) The origin of the dark matter.
f) The origin of the matter-antimatter asymmetry.
g) And several other open problems.
The spin-charge-family theory, a kind of the Kaluza-Klein theories in (d=(2n-1)+1) space-time, with d=(13+1) and the two kinds of the spin connection fields, which are the gauge fields of the two kinds of the Clifford algebra objects anti-commuting with one another, is promising to provide this much needed next step.

Keynote: Classical Lagrangian formulation of local gauge U(1) and SU(3) fields in terms of field strength magnitudes described in Weyl two-spinor language and induced Zitterbewegung (trembling motion) in spin 1/2 particles via gauge field U(1) transformations
Time : 10:10-10:50
J Buitrago is a Professor of Physics at the University of La Laguna in Tenerife, Spain. His research activities have been on a wide range of disciplines such as General Relativity, Relativistic Quantum Theory, Gauge Theories, Cosmology, some areas of Astrophysics, Gravitational Waves and Cosmology. He has imparted undergraduate and graduate courses on Astrophysics, Nuclear Physics, General Relativity, Cosmology and Gauge Theories. He has directed five doctoral thesis and published more than 30 articles. He was also visiting fellow during six months at the University College of Cardiff as well as three months in Cambridge.
After a discussion about classical local U(1) and SU(3) gauge invariance theories in Weyl two-spinor form (in terms of the electric and magnetic field strength components as well as the color field components) and the associated two spinor equations equivalent to the Lorentz Force equation of electrodynamics. The local U(1) gauge transformation properties of the different components of the symmetric second order electromagnetic field spinor are analyzed. It is found that only the third component of the magnetic field is changed by local gauge transformations. Using the gauge freedom associated with the third component of the magnetic field and choosing a specific gauge (in a somewhat similar manner as the familiar Coulomb gauge in QED) it is shown that the phenomenon of Zitterbewegung (trembling motion) appears in a natural way as internal motion with the velocity of light applicable to any one-half spin particle thus suggesting a kinematic origin of its rest mass and helicity. This result is in sharp contrast with the traditional interpretation (emerging from the Dirac equation) as transitions between positive and negative energy states.
