Femtoscopy of the <i>J/?</i>-nucleon interaction

چکیده
I discuss the prospects of using femtoscopy in high-energy protonproton and heavy-ion collisions to learn about low-energy J/? -nucleon interaction. Femtoscopy is a technique that makes it possible obtain spatiotemporal information on particle production sources at femtometer scale through measurements two-hadron momentum correlation functions. These functions also provide hadron-hadron forces as final-state effects. In particular, such give access forward scattering amplitude. One can express amplitude product chromopolarizability nucleon’s average chromoelectric gluon distribution, latter being relevant problem origin nucleon mass. will present results recent study interaction from lattice QCD simulations compute The calculated show clear sensitivity conclude discussing open issues regarding use effective range expansion formula fit experimental data for small lengths large parameters.

The Nucleon-Nucleon Interaction
Recent developements in our understanding of the fundamental nucleon-nucleon interaction are reviewed. Among the topics considered are (1) the so-called high-precision nucleon-nucleon potentials that emerged in the mid 1990s, (2) progress in the microscopic description of the intermediate-range part of the nucleon-nucleon interaction in terms of correlated pion-pion and rho-pion exchange and (3...
متن کاملThe nucleon - nucleon interaction
We review the major progress of the past decade concerning our understanding of the nucleon-nucleon interaction. The focus is on the low-energy region (below pion production threshold), but a brief outlook towards higher energies is also given. The items discussed include charge-dependence, the precise value of the πN N coupling constant, phase shift analysis and high-precision NN data and pote...
متن کاملChiral Symmetry and the Nucleon-Nucleon Interaction
The main progress in the eld of nucleon-nucleon (NN) potentials, which we have seen in recent years, is the construction of some very quantitative (high-quality/high-precision) NN potentials. These potentials will serve as excellent input for microscopic nuclear structure calculations and will allow for a systematic investigation of o -shell effects. After this enormous quantitative work, it is...
متن کاملSeparable Kernel of Nucleon - Nucleon Interaction in the Bethe - Salpeter
The solution for the nucleon-nucleon (NN) T matrix in the framework of the covariant Bethe-Salpeter approach for a two spin-one-half particle system with a separable kernel of interaction is analyzed. The explicit analytical connection between parameters of the separable kernel and low energy scattering parameters, deuteron binding energy and phase shifts is established. Covariant separable ker...
متن کاملNucleon-Nucleon Interaction Models and Non-Locality
The effect of non-locality in the NN interaction models is examined. It is shown that this feature can explain differences in predictions made from models evidencing a difference with this respect. This is done for both static and dynamical observables, taking into account that a non-local term can be transformed away by performing a unitary transformation. Some results for the deuteron form fa...
