ON POSSIBLE IMPLICATIONS OF A LARGE cT(e+e- - hadrons)*
Based upon the notion fiat the large cross section observed in -!-ee hadrons may be due to a kind of hadronic core inside the electron, it is suggested that there may also be a large cross section for e-ehadrons and further that lepton number may not be conserved in the latter reaction.

متن کاملPossible Existence of a Heavy Neutral Meson
efIiciency of (3.1+0.4)%, compatible with the value e=3.3% computed with the formula given above. Reversely, the experimental result together with the computed efficiency can be considered as a check on the v/c law for the polarization of electrons emitted in p decay. We have made P—y coincidence measurements with Co". The difference in coincidence counting rates (corrected as described in the ...
متن کاملRadiative processes of nucleon interactions and possible existence of exotic
Radiative processes of nucleon interactions and possible existence of exotic dibaryons 1. Abstract The cross section of the reaction pp → ppγγ is estimated and the exploration possibilities of this reaction to probe for a possible excitation of subnuclear degrees of freedom in two-nucleon systems, in particular, the production and decay of the NN-decoupled dibaryon resonances, are briefly discu...
متن کاملPossible Existence of Melanocytes or Melanoblasts in Human Sebaceous Glands
BACKGROUND Melanocytes are present in both basal epidermis and hair follicles. Melanocyte stem cells have been found in hair follicle bulge. During embryogenesis, the outer cells of the bulge differentiate into the sebaceous gland (SG) and proliferate. OBJECTIVE To identify and determine the distribution and morphological characteristics of melanocytes in human SGs. METHODS A total of 171 b...
متن کاملGrowth of pagoda-topped tetragonal copper nanopillar arrays.
Growth of arrays of pagoda-topped tetragonal Cu nanopillar (length 1- 6 mum; width 150 +/- 25 nm) with {100} side faces on Au/glass is achieved by a simple electrochemical reduction of CuCl(2)(aq) by Al(s) in aqueous dodecyltrimethylammonium chloride. Field-emission measurement shows that the Cu nanopillars can emit electrons (10 muA cm(-2)) at a turn-on field of 12.4 V mum(-1) with a calculate...
