Selectron Studies at e-e- and e+e- Colliders [PDF]

open access: yes, 2001
Selectrons may be studied in both e-e- and e+e- collisions at future linear colliders. Relative to e+e-, the e-e- mode benefits from negligible backgrounds and threshold behavior for identical selectron pair production, but suffers from luminosity degradation and increased initial state radiation and beamstrahlung. We include all of these effects and

Inclusive (e, e′ N), (e, e′ NN), (e, e′ π), …v reactions in nuclei [PDF]

open access: yesNuclear Physics A, 1997
We study the inclusive (e,e'N), (e, e'NN), (e,e'pi), (e,e'pi N) reactions in nuclei using a Monte Carlo simulation method to treat the multichannel problem of the final state. The input consists of reaction probabilities for the different steps evaluated using microscopical many body methods.

S_3 Flavor Symmetry and Leptogenesis

open access: yes, 2005
We consider leptogenesis in a minimal S_3 extension of the standard model with an additional Z_2 symmetry in the leptonic sector. It is found that the CP phase appearing in the neutrino mixing is the same as that for the CP asymmetries responsible for ...

The cross section for e+e−→e+e−e+e−

open access: yesNuclear Physics B, 1984
Abstract A calculation of the cross section for the process e + e − →e + e − e + e − is presented. The complete set of 36 Feynman diagrams is taken into account and is computed at the amplitude level, neglecting the electron mass. Emphasis is placed on the requirement for any such calculation that it can be done numerically in a fast and simple way.

open access: yesLinha Mestra, 2020
A presente pesquisa busca investigar os agenciamentos entre desejo e aprendizagem. Para tanto, vislumbramos a possibilidade de pensar a partir do conceito de minoridade no pensamento criado por Deleuze e Guattari (2017) e deslocado para o campo da educação por Gallo (2002).
