Suppression effect of the ionization produced by electron-positron pairs of extremely high energy

doi:10.1080/14786435808237003

“…In Fig. 2 is shown some slightly more recent measurements by Iwadare [22], also based on tracks in emulsions. The agreement between theory and experiment is generally good, although the assignment of energy to a specific pair event is connected with systematic errors -depending on the chosen method -of up to a factor 5 [22, Fig.…”

“…The Chudakov effect has been studied experimentally with the use of cosmic ray photons for pair production in emulsions [13,16,17], which showed a fairly good agreement with the theories of this effect for the mean ionization loss of the pair [12,[18][19][20][21]. In [22,23] there was reported the first proof-of principle experiment of this kind, where the photons were generated by high-energy electrons in an accelerator.…”

The ionization loss of a high-energy electron-positron pair in thin targets is considered. The analogue of the Landau distribution function is derived for this loss under the condition when the Chudakov effect of the pair ionization loss suppression is manifested. Expression for the most probable value of the pair ionization loss E MP is obtained. It is shown that the magnitude of Chudakov effect for E MP can be noticeably different from the magnitude of this effect for the restricted mean value of the pair ionization loss. The obtained results are applied to the analysis of experimental measurements of high-energy electron-positron pair ionization loss in thin silicon detectors.

The ionization loss of a high-energy electron–positron pair in thin targets is considered. The targets not thinner than about 10 $$\upmu $$ μ m are discussed. The analogue of the Landau distribution function is derived for this loss under the condition when the Chudakov effect of the pair ionization loss suppression is manifested. Expression for the most probable value of the pair ionization loss $$E_{MP}$$ E MP is obtained. It is shown that the magnitude of Chudakov effect for $$E_{MP}$$ E MP can be noticeably different from the magnitude of this effect for the restricted mean value of the pair ionization loss.
