We have determined theoretically the rest mass of the muon neutrino at 50 milli-eV and the rest mass of the electron neutrino at 5 meV, as well as , to 1% accuracy, the ratio of the masses of the stable elementary particles which decay by weak decays. We assume that the particles of the neutrino branch consist of a cubic, isotropic nuclear lattice, held together by the weak nuclear force. The e...
The theory of symmetry breaking in presence of gauge fields is presented, following the historical track. Particular emphasis is placed upon the underlying concepts. Invited talks presented at the 2001 Corfu Summer Institute on Elementary Particle Physics 2 E-mail : [email protected]
It is shown that particle motion in a bent (straight) crystal is accompanied by particle spin rotation and oscillations that allows to measure the tensor electric polarizability of nuclei and elementary particles.
We describe a geometric picture for the pattern of fermion masses of the three generations which is invariant with respect to the renormalization group below the electroweak scale. Moreover, we predict the upper limit for the ratio between the Dirac masses of the μ and τ neutrinos, ( mνμ/mντ ) ≤ (9.6 ± 0.6) × 10. The Standard Model [1, 2] of strong and electroweak interactions describes accurat...
D ebates on the origin of life—or more precisely the terrestrial origin of life—as well as the origin of the universe are followed with great interest in almost all human societies. In the latter case, there exists a standard model, the big bang theory derived from an extrapolation of elementary particle physics to the birth of our universe. Nothing comparable is at hand for origin of life stud...
A search for a two-body transition Υ (3S) → γA0, where A0 is a light scalar particle, followed by its decay into 2 muons has been performed using a data sample of (121 ± 1.2) × 106 Υ (3S) decays. As ΓΥ (4S)/ΓΥ (3S) ≈ 10 3, one has greater sensitivity to rare decays using Υ (3S) decays than Υ (4S) samples. The Standard Model (SM) predicts the existence of the Higgs boson to account for the diffe...
We consider what occurs when we remove one of the compositeness conditions proposed by Bardeen, Hill and Lindner that leads to predictions for the top quark mass conflicting with the experimental value. Through this consideration the condition for the Higgs particle to be the composite particle is reconsidered. We show that in this case, (I) the Higgs-Yukawa system of the standard model becomes...
We present certain classical continuum long wave-length limits of prototype integrable quantum spin chains, and define the corresponding construction of classical continuum Lax operators. We also provide two specific examples, i.e. the isotropic and anisotropic Heisenberg models. ∗Proceedings contribution to the Corfu Summer Institute on Elementary Particle Physics and Gravity Workshop on Non C...
Abstract: I show that there exists a class of inequalities between correlation functions of different orders of a chaotic electron field. These inequalities lead to the antibunching effect and are a consequence of the fact that electrons are fermions – indistinguishable particles with antisymmetric states. The derivation of the inequalities is based on the known form of the correlation function...
We consider diffractive processes which can be measured at the LHC. Analysis of diffractive events will give unique information about the high energy asymptotics of hadron scattering. In semihard diffraction one may study the partonic structure of the Pomeron. Central Exclusive Diffractive production provides a possibility to investigate the new particles (Higgs bosons, SUSY particles,...) in a...
