How to calculate cross section in lhc
WebAlso the recent electron g − 2 measurement at Harvard contributes substantially to the progress in this field, as it allows for a much more precise determination of the fine structure constant α as well as a cross check of the status of our theoretical understanding.In this report we review the theory of the anomalous magnetic moments of the electron and the … Web1 nov. 2011 · After applying the optical theorem the total proton–proton cross section is σ tot =(110.6 ± 3.4 ) mb, well in agreement with the extrapolation from lower energies. This method also allows one to derive the luminosity-independent elastic and inelastic cross sections σ el =(31.0 ± 1.7) mb and σ inel =(79.5 ± 1.8) mb .

WebThe cross section dσ=dk⊥ for the γ −P=R-fusion processes gradually increases and reaches a maximum at k⊥ ≃0.25 GeV. The purely dif-fractive CEP fusion processes, R− −P and O−P,give much smaller cross sections there. For the photon brems-strahlung, discussed in [2], the cross section for k⊥ → 0 diverges as 1=k⊥.
