Klein Paradox in Bosons
We show analytically that the Zitterbewegung and Klein Paradox, such well known aspects of the Dirac Equation are not found in the case of Bosons. We use the Kemmer-Duffin-Harish Chandra formalism with β matrices to arrive at our results.
متن کاملBosonic analog of the Klein paradox
The standard Klein paradox describes how an incoming electron scatters off a supercritical electrostatic barrier that is so strong that it can generate electron-positron pairs. This fermionic system has been widely discussed in textbooks to illustrate some of the discrepancies between quantum mechanical and quantum field theoretical descriptions for the pair creation process. We compare the fer...
متن کاملBarrier Paradox in the Klein Zone
We study the solutions for a one-dimensional electrostatic potential in the Dirac equation when the incoming wave packet exhibits the Klein paradox (pair production). With a barrier potential we demonstrate the existence of multiple reflections (and transmissions). The antiparticle solutions which are necessarily localized within the barrier region create new pairs with each reflection at the p...
متن کاملHistory and Physics of The Klein Paradox
The early papers by Klein, Sauter and Hund which investigate scattering off a high step potential in the context of the Dirac equation are discussed to derive the ’paradox’ first obtained by Klein. The explanation of this effect in terms of electron-positron production is reassessed. It is shown that a potential well or barrier in the Dirac equation can become supercritical and emit positrons o...
متن کاملKaluza–Klein excitations of gauge bosons at the LHC
We consider the Randall-Sundrum extra dimensional model with fields propagating in the bulk based on an extended electroweak gauge symmetry with specific fermion charges and localizations that allow to explain the LEP anomaly of the forward– backward asymmetry for b–quarks, AFB. We study the manifestations of the strongly– interacting and electroweak gauge boson Kaluza–Klein excitations VKK at ...
