Charmed-meson scattering on nucleons in a QCD Coulomb gauge quark model
The scattering of charmed mesons on nucleons is investigated within a chiral quark model inspired on the QCD Hamiltonian in Coulomb gauge. The microscopic model incorporates a longitudinal Coulomb confining interaction ...
The interaction of D mesons and nucleons at finite density
We present results on the the influence of changes in the masses and sizes of D mesons and nucleons on elastic DN scattering cross sections and phase shifts in a hadronic medium composed of confined quarks in nucleons. We ...
Relativistic three-body model for final state interaction in D+ → K-π+π+ decay
A challenge in mesonic three-body decays of heavy mesons is to quantify the contribution of re-scattering between the final mesons. D decays have the unique feature that make them a key to light meson spectroscopy, in ...
Chiral symmetry and pion-nucleon scattering
(World Scientific Publ Co Pte Ltd, 1997-01-01)
In this work, we study the influence of the way pious couple to nucleons in perturbative calculation of an observable in the pion-nucleon scattering.
Asymptotic Scenarios for the Proton's Central Opacity: An Empirical Study
(Amer Inst Physics, 2015-01-01)
We present a model-independent analysis of the experimental data on the ratio X between the elastic and total cross-sections from pp and p (p) over bar scattering in the c.m. energy interval 5 GeV - 8 TeV. Using a novel ...
Stopping power and depth dose profile of H+ and He+ ion beams in hydroxyapatite thin films.
(Gdańsk University of TechnologySopot, 2013-05-20)
Hadron therapy is a promising technique to treat deep-seated tumors. For an accurate treatment planning, the energy deposition in the soft and hard human tissue must be well known. Water has been usually employed as a ...
Scattering process in the Scalar Duffin-Kemmer-Petiau gauge theory
(Iop Publishing Ltd, 2016-01-01)
In this work we calculate the cross section of the scattering process of the Duffin-Kemmer-Petiau theory coupling with the Maxwell's electromagnetic field. Specifically, we find the propagator of the free theory, the ...
A Study of Scattering Amplitude Regularization in the NN System: Two Pions Contributions
(Amer Inst Physics, 2010-01-01)
In a simplest case we employ dimensional regularization method in order to evaluate the contribution of two pion exchanges to the NN interaction. The method allows one to treat the infinities of scattering amplitude in a ...
