Content
We analyze the low-|t| elastic differential cross-section data for proton–proton and proton–antiproton scattering from SPS to LHC energies using a simple Lévy α-stable (SL) model. This approach successfully describes the data with a statis- tically significant non-exponential behavior. The energy dependence of the model parameters is determined, showing that the Lévy exponent remains approximately energy-independent with α = 1.959 ± 0.002. We also investigate the tension between the TOTEM and ATLAS measurements of dσpp/dt at 7, 8, and 13 TeV, finding that the discrepancy arises only from normalization differences, not from the shape of the |t|-distribution.
