On the neutron-antineutron oscillations
L. B. Okun
This is a draft of my brief note on the early history of oscillations written for the Project X at the request of Chris Quigg in March 2013.
The impact of the Sakata model
L. B. Okun
The evolution of the Sakata model is described on the basis of personal recollections, proceedings of international conferences on high energy physics and some journal articles.
Mirror particles and mirror matter: 50 years of speculation and search
L. B. Okun
This review describes the history of discovery of violation of spatial parity P, charge conjugation parity C, combined parity CP. The hypothesis of existence of mirror particles wa…
Photon: history, mass, charge
L. B. Okun
The talk consists of three parts. ``History'' briefly describes the emergence and evolution of the concept of photon during the first two decades of the 20th century. ``Mass'' give…
Neutrino wave function and oscillation suppression
A. D. Dolgov, O. V. Lychkovskiy, A. A. Mamonov +2
We consider a thought experiment, in which a neutrino is produced by an electron on a nucleus in a crystal. The wave function of the oscillating neutrino is calculated assuming tha…
Oscillations of neutrinos produced and detected in crystals
A. D. Dolgov, O. V. Lychkovskiy, A. A. Mamonov +3
We analyze neutrino oscillations in a thought experiment in which neutrinos are produced by electrons on target nuclei. The neutrinos are detected through charged lepton production…
On the charge of the photon
L. B. Okun
The papers setting upper bounds on the value of electric charge of the photon are briefly reviewed. The theoretical framework of these bounds is shown to be incomplete. Hence the b…
Oscillations of neutrinos produced by a beam of electrons
A. D. Dolgov, L. B. Okun, M. V. Rotaev +1
We analyze a thought neutrino oscillation experiment in which neutrinos are produced by electrons colliding with atomic nuclei of a target. The neutrinos are detected by observing…
Plane waves and wave packets in particle oscillations
L. B. Okun, M. V. Rotaev, M. G. Schepkin +1
Manipulation with ill-defined notions creates an illusion of a simple derivation of the standard phase of neutrino oscillations in hep-ph/0311241 and hep-ph/0312180.
A remark on the "Theory of neutrino oscillations"
L. B Okun, M. V. Rotaev, M. G. Schepkin +1
It is shown that the derivation of standard oscillation phase in the plane wave approximation without equal energy assumption is fraught with inconsistencies.
Z-lineshape versus 4th generation masses
S. S. Bulanov, V. A. Novikov, L. B. Okun +2
The dependence of the Z-resonance shape on the location of the threshold of the N\bar{N} production (N is the 4th generation neutrino) is analyzed. The bounds on the existence of 4…
Proceedings to the Workshops ''What comes beyond the Standard model'' 2000,2001, VOLUME 1: Festschrift dedicated to the 60th birthday of Holger Bech Nielsen
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…
On the extra factor of two in the phase of neutrino oscillations
L. B. Okun, M. G. Schepkin, I. S. Tsukerman
Attempts to modify the standard expression for the phase in neutrino oscillations by an extra factor of two are based on misuse of quantum mechanics. Claims to present Bruno Pontec…
C, P, T are Broken. Why Not CPT?
L. B. Okun
Classification of effects of violation of seven symmetries -- C, P, T, CP, PT, TC, and CPT -- is discussed. A graphic mnemonic scheme -- CPT-cube -- is suggested and illustrated by…
Cube or hypercube of natural units
L. B. Okun
Max Planck introduced four natural units: h, c, G, k. Only the first three of them retained their status, representing the so called cube of theories, after the theory of relativit…
Extra generations and discrepancies of electroweak precision data
V. A. Novikov, L. B. Okun, A. N. Rozanov +1
It is shown that additional chiral generations are not excluded by the latest electroweak precision data if one assumes that there is no mixing with the known three generations. In…
Historical roots of gauge invariance
J. D. Jackson, L. B. Okun
Gauge invariance is the basis of the modern theory of electroweak and strong interactions (the so called Standard Model). The roots of gauge invariance go back to the year 1820 whe…
Photons and static gravity
L. B. Okun
The influence of static gravitational field on frequency, wave-length and velocity of photons and on the energy levels of atoms and nuclei is considered in the most elementary way.…
On the search for 50 GeV neutrinos
V. A. Ilyin, M. Maltoni, V. A. Novikov +3
Using the computer code CompHEP we estimate the number of events and the background, at LEP II and TESLA, for the reaction , where is a hypothetical Dira…
Extra quark-lepton generations and precision measurements
M. Maltoni, V. A. Novikov, L. B. Okun +2
The existence of extra chiral generations with all fermions heavier than M_Z is strongly disfavoured by the precision electroweak data. However the data are fitted nicely even by a…
Electroweak Working Group Report
D. Bardin, W. Beenakker, M. Bilenky +14
The report summarizes the results of the activities of the Working Group on Precision Calculations for the Z Resonance at CERN during 1994.
Do muons oscillate ?
A. D. Dolgov, A. Yu. Morozov, L. B. Okun +1
We develop a theory of the EPR-like effects due to neutrino oscillations in the decays. Its experimental implications are space-time correlations of neutrino and muon whe…
