In this presentation, we present a simple methodology for formation and hierarchical assembly of electrically addressable nanowire-based semiconductor heterojunctions. These p-n junctions are oriented and formed epitaxially by planar growth of nanowires on a semiconductor substrate, as opposed to conventional approaches that use mechanical contacts. We demonstrate a practical two-step approach for...
Using perturbative quantum chromodynamics and quark–diquark model of baryons, we have obtained an analytical fragmentation function which describes Ωbbc and Ωbcc baryons in b and c quarks fragmentation. The universal fragmentation probabilities, the average fragmentation parameters and the production cross sections resulting from this function are in a very good agreement with those obtained using...
We investigate the relativistic Fermi motion effect in the case of J/ψ production in various hadron colliders. A light-cone wave function is adopted to represent the J/ψ final state. The change in the confinement parameter which sets a scale for the size of the final state, allows one to see the effect in an explicit manner. While the effect has considerable influence on the fragmentation probabilities...
