Employing the fermion unification model based on the intrinsic SU(8) symmetry of a generalized Dirac equation, we discuss the fundamental interactions under the SU(8)=SU(2)⊗SU(4) symmetry group. The physics involved can describe all fermions, the leptons (electron and neutrino), and the colored up and down quarks of the first generation in the standard model (SM) by a complex SU(8) octet of Dir...

We consider U(1) gauge fields in a slice of AdS5 with bulk and boundary mass parameters. The zero mode of a bulk U(1) gauge field can be localized either on the UV or IR brane. This leads to a simple model of millicharged particles in which fermions can have arbitrarily small electric charge. In the electroweak sector we also discuss phenomenological implications of a localized U(1)Y gauge boso...

Inspired by Stillman Drake’s definition of G&lean Units as those for which & = (g)g where g is any finite, constant acceleration measured in units of L and T, we construct a lcinematical dimensional analysis based only on two universal, dimensionless constants. For the linear relation between L and T we use Einsteinian Units 6 = (1)~. For orbiting masses negligible compared to some mass unit M,...

The Large Hadron Collider with its ATLAS and CMS detectors will soon provide us with data to explore a new energy scale. Although already the very first data may contain surprises the first concluding results for the search for new physics are expected with the full 2009 data, where the LHC is expected to operate at √ s = 14 TeV. This article summarises the recent prospects for Supersymmetry (S...

We introduce and analyze a system of relativistic fermions in a spacetime continuum, which interact via an action principle as previously considered in a discrete space-time. The model is defined by specifying the vacuum as a sum of Dirac seas corresponding to several generations of elementary particles. The only free parameters entering the model are the fermion masses. We find dynamical field...

In this talk we examine how one-loop soft and collinear splitting functions occur in the calculation of next-to-next-to-leading order (NNLO) corrections to production rates, and we present the one-loop gluon soft and splitting functions, computed to all orders in the dimensional regularization parameter ǫ. We apply the one-loop gluon soft function to the calculation of the next-to-leading logar...

The quest of a vanishing cosmological constant is considered in the simplest anomaly-free chiral gauge extension of the electroweak standard model where the new physics is limited to a well defined additional flavordynamics above the Fermi scale, namely up to a few TeVs by matching the gauge coupling constants at the electroweak scale, and with an extended scalarland. In contrast to the electro...

stability of the ;-; stacking interactions in the substituted-coronene||cyclooctatetraene complexes wasstudied using the computational quantum chemistry methods (where || denotes ;–; stackinginteraction, and substituted-coronene is coronene which substituted with four similar x groups; x =oh, sh, h, f, cn, and no). there are meaningful correlations between changes of geometricalparameters and t...

We propose a derivation of the empirical Weinberg relation for the mass of an elementary particle and in an inflationary type of universe. Our derivation produces the standard well known Weinberg relation for the mass of an elementary particle, along with an extra term which depends on the inflationary potential, as well as Hubble’s constant. The derivation is based on Zeldovich’s result for th...
