After the recent incident, we have restored access to the website from outside the CERN network, however access from certain worldwide locations is still being blocked.

The incoming electron (E, $\vec{p_{\mathrm{e}}}$) interacts with the nucleus (A, Z) of the traversed matter; the emitted photon carries a momentum $\vec{k}$ and the outgoing electron (E$'$, $\vec{p_{\mathrm{e}}}'$).

Fractional energy loss per radiation length as a function of electron or positron energy in lead
Bi-dimensional distribution of $\frac{\textrm{d}E}{\textrm{d}x}$ and momentum for ATLAS 2010 data. The distributions of the most probable value for the fitted probability density functions of pions (black), kaons (grey), and protons (blue), in different track categories, are superimposed.
The incoming photon ($\vec{k}$) interacts with the EM field of the nucleus (A,\,Z): an electron ($\mathrm{E},\vec{p_{\mathrm{e}}}$), positron ($\mathrm{E}^\prime, \vec{p_{\mathrm{e}}}^\prime$) pair is created.
