We study the holographic Schwinger effect with magnetic field at RHIC and LHC energies by using the AdS/CFT correspondence. We consider both weak and strong magnetic field cases with B\ll T^2 and B\gg T^2 solutions respectively. Firstly, we calculate separating length of the particle pairs at finite magnetic field.

Webbmained poorly deﬁned; but Schwinger believed throughout his life that his approach was “more general, more elegant, more useful, and more tied to the historical line of development as the quantum transcription of Hamilton’s action principle” [Schwinger 1973]. Later, in a tribute to Feynman, Schwinger commented further. Dirac, of Webb8 sep. 2024 · Using the gauge-gravity duality, we study the holographic Schwinger effect by performing the potential analysis on the confining D3- and D4-brane background with D-instantons then evaluate the pair production/decay rate by taking account into a fundamental string and a single flavor brane respectively.
