Influence of Complex Formation on Mutual Diffusion in Benzene-Chloroform

Peculiarities of diffusion in the mixture of molecular liquids are connected with intermolecular interactions. Theory of nonlinear diffusion takes into account the effect of molecular complexes formation in liquid mixtures

Electromagnetic structure of the nucleon and the Roper resonance in a light-front quark approach

A relativistic light-front quark model is used to describe both the elastic nucleon and nucleon-Roper transition form factors in a large Q2 range, up to 35 GeV2 for the elastic and up to 12 GeV2 for the resonance case. Relativistic three-quark configurations satisfying the Pauli exclusion principle on the light-front are used for the derivation of the current matrix elements. The Roper resonance is considered as a mixed state of a three-quark core configuration and a molecular N+sigma hadron component. Based on this ansatz we obtain a realistic description of both processes, elastic and inelastic, and show that existing experimental data are indicative of a composite structure of the Roper resonance.Comment: 19 page
