The Bialas–Bzdak model of elastic proton–proton scattering assumes a purely imaginary forward scattering amplitude, which consequently vanishes at the diffractive minima. We extended the model to arbitrarily large real parts in a way that constraints from unitarity are satisfied. The resulting model is able to describe elastic pp scattering not only at the lower ISR energies but also at [Formula: see text] in a statistically acceptable manner, both in the diffractive cone and in the region of the first diffractive minimum. The total cross-section as well as the differential cross-section of elastic proton–proton scattering is predicted for the future LHC energies of [Formula: see text], 14, 15 TeV and also to 28 TeV. A nontrivial, significantly nonexponential feature of the differential cross-section of elastic proton–proton scattering is analyzed and the excitation function of the nonexponential behavior is predicted. The excitation function of the shadow profiles is discussed and related to saturation at small impact parameters.

An external proton beam from the 110 in. Harwell cyclotron has been used to investigate proton-proton scattering at 147 MeV. The angular distribution of the scattering has been studied from 25 to 90° and found to be isotropic, within the limits of error. The absolute differential cross-section for scattering at 90° has been measured in two ways and found to be 4⋅94 ± 0⋅28 millibams. The results can also be used to find the 12 C( p , pn ) 11 C cross-section at 142 MeV.

AbstractThe unitarily extended Bialas–Bzdak model of elastic proton–proton scattering is applied, without modifications, to describe the differential cross-section of elastic proton–antiproton collisions in the TeV energy range, and to extrapolate these differential cross-sections to LHC energies. In this model-dependent study we find that the differential cross-sections of elastic proton–proton collision data at 2.76 and 7 TeV energies differ significantly from the differential cross-section of elastic proton–antiproton collisions extrapolated to these energies. The elastic proton–proton differential cross-sections, extrapolated to 1.96 TeV energy with the help of this extended Bialas–Bzdak model do not differ significantly from that of elastic proton–antiproton collisions, within the theoretical errors of the extrapolation. Taken together these results provide a model-dependent, but statistically significant evidence for a crossing-odd component of the elastic scattering amplitude at the at least 7.08 sigma level. From the reconstructed Odderon and Pomeron amplitudes, we determine the $$\sqrt{s}$$ s dependence of the corresponding total and differential cross-sections.

Abstract The TOTEM collaboration has measured the elastic proton-proton differential cross section $$\mathrm{d}\sigma /\mathrm{d}t$$dσ/dt at $$\sqrt{s}=13$$s=13 TeV LHC energy using dedicated $$\beta ^{*}=90$$β∗=90 m beam optics. The Roman Pot detectors were inserted to 10$$\sigma $$σ distance from the LHC beam, which allowed the measurement of the range [0.04 GeV$$^{2}$$2; 4 GeV$$^{2}$$2$$]$$] in four-momentum transfer squared |t|. The efficient data acquisition allowed to collect about 10$$^{9}$$9 elastic events to precisely measure the differential cross-section including the diffractive minimum (dip), the subsequent maximum (bump) and the large-|t| tail. The average nuclear slope has been found to be $$B=(20.40 \pm 0.002^{\mathrm{stat}} \pm 0.01^{\mathrm{syst}})~$$B=(20.40±0.002stat±0.01syst)GeV$$^{-2}$$-2 in the |t|-range 0.04–0.2 GeV$$^{2}$$2. The dip position is $$|t_{\mathrm{dip}}|=(0.47 \pm 0.004^{\mathrm{stat}} \pm 0.01^{\mathrm{syst}})~$$|tdip|=(0.47±0.004stat±0.01syst)GeV$$^{2}$$2. The differential cross section ratio at the bump vs. at the dip $$R=1.77\pm 0.01^{\mathrm{stat}}$$R=1.77±0.01stat has been measured with high precision. The series of TOTEM elastic pp measurements show that the dip is a permanent feature of the pp differential cross-section at the TeV scale.
