Quarks in nuclear medium
Using the quark-meson coupling (QMC) model we study nuclear matter from the point of view of quark degrees of freedom. As the nucleon model we adopt the MIT bag model and the relativistic constituent quark model, where a square well and harmonic oscillator potentials are used to confine the quarks. We introduce the Lorentz-vector type confining potential as well as the Lorentz-scalar type one i...
متن کامل→ ππ decay in nuclear medium ⋆
We calculate the width for the ω → ππ decay in nuclear medium. Chiral dynamics and low-density approximation are used. At densities around twice the nuclear saturation density we estimate the partial width for the decay of the longitudinal mode to be of the order of a few tens of MeV, and for the transverse mode a few times less.
متن کاملMesons in the nuclear Medium
We discuss recent experimental results on the modification of hadron properties in a nuclear medium. Particular emphasis is placed on an ω production experiment performed by the CBELSA/TAPS collaboration at the ELSA accelerator. The data shows a smaller ω meson mass together with a significant increase of its width in the nuclear medium.
متن کاملHadrons in the Nuclear Medium
In this talk I first discuss predictions based on QCD sum rules and on hadronic models for the properties of vector mesons in the nuclear medium. I then describe possible experimental signatures and show detailed predictions for dilepton invariant mass spectra with a special emphasis on nuclear reactions involving elementary incoming beams and nuclear targets. I will in particular illustrate th...
متن کاملVector Meson in Nuclear Medium
Vector mesons immersed in nuclear medium are expected to change their properties due to partial chiral symmetry restoration and/or many body nuclear effects. Expected changes range from the decrease in the mass,1),2) increase in the width,3)–7) and appearance of new structures,8),9) every aspect of which if measured will lead to a new understanding of strong interaction. Several experiments are...
