Elastic Amplitudes and Observables in pp Scattering
Erasmo Ferreira, Takeshi Kodama, Anderson Kendi Kohara
Using a unified analytic representation for the elastic scattering amplitudes of pp scattering valid for all high energy region, the behavior of observables in the LHC collisions i…
pp Elastic Scattering at LHC Energies
Anderson Kendi Kohara, Erasmo Ferreira, Takeshi Kodama
Using a unified analytic representation for the elastic scattering amplitudes of pp scattering valid for all energy region, the behavior of observables in the LHC collisions in the…
pp Interaction at Very High Energies in Cosmic Ray Experiments
A. Kendi Kohara, Erasmo Ferreira, Takeshi Kodama
An analysis of p-air cross section data from Extensive Air Shower (EAS) measurements is presented, based on an analytical representation of the pp scattering amplitudes that descri…
Two-point derivative dispersion relations
Erasmo Ferreira, Javier Sesma
A new derivation is given for the representation, under certain conditions, of the integral dispersion relations of scattering theory through local forms. The resulting expressions…
One-dimensional quantum scattering by a parabolic odd potential
Erasmo M. Ferreira, Javier Sesma
Quantum scattering by a one-dimensional odd potential proportional to the square of the distance to the origin is considered. The Schrödinger equation is solved exactly and explici…
An algebraically solvable PT-symmetric potential with broken symmetry
E. M. Ferreira, J. Sesma
The spectrum of a one-dimensional Hamiltonian with potential for negative and for positive is analyzed. The Schrödinger equation is algebraically s…
