Elastic Cross sections for high energy hadron-hadron scattering
نویسنده
چکیده
This report discusses some results on differential cross sections for high energy and small momentum transfer elastic hadron-hadron scattering in QCD, using a functional integral approach. In particulary a matrix cumulant expansion for the vacuum expectation values of lightlike Wegner-Wilson loops, which governs the hadronic amplitudes, is presented. The cumulants are evaluated using the model of the stochastic vacuum.

Differential cross sections for high energy elastic hadron-hadron scattering in nonperturbative QCD
Total and differential cross sections for high energy and small momentum transfer elastic hadron-hadron scattering are studied in QCD using a functional integral approach. The hadronic amplitudes are governed by vacuum expectation values of lightlike Wegner-Wilson loops, for which a matrix cumulant expansion is derived. The cumulants are evaluated within the framework of the Minkowskian version...
متن کاملLattice approach to high–energy hadron–hadron scattering
The prediction from first principles of total cross sections at high energy is one of the oldest open problems of hadronic physics. Present– day experimental data are well described by a universal pomeron–like power–law behaviour (see, for example, Ref. [1] and references therein), σ (hh) tot (s) ∼ s→∞ (s/s0) ǫP , where the so–called soft pomeron intercept is ǫP ≃ 0.08, but this is forbidden as...
متن کاملForm of analyzing power and the determination of the basic parameters of hadron scattering amplitude ”
The determination of magnitudes of basic parameters of the high energy elastic scattering amplitude are examined at small momentum transfers with taking account of the Coulomb-hadron interference effects. An actual problem of the modern elementary particles physics, the research of strong interaction processes at large distances and high energies, is considered in the framework of different app...
متن کاملHigh - energy elastic hadron collisions and space structure of hadrons
The elastic and inelastic profiles have been derived from the measured elastic differential cross section data with the help of exact impact parameter representation of elastic scattering amplitude. The results obtained for pp scattering at energy of 53 GeV and ¯ pp scattering at energy of 541 GeV have been presented. They indicate that nucleons can be regarded as objects characterized by a sma...
متن کاملNonperturbative QCD treatment of high-energy hadron-hadron scattering.
Total cross-sections and logarithmic slopes of the elastic scattering crosssections for different hadronic processes are calculated in the framework of the model of the stochastic vacuum. The relevant parameters of this model, a correlation length and the gluon condensate, are determined from scattering data, and found to be in very good agreement with values coming from completely different so...
