In-medium Properties of Hadrons
نویسنده
چکیده
A diverse experimental program for the study of the photoproduction of mesons off nuclei has been carried out and is still running at the Mainz MAMI and Bonn ELSA electron accelerators with the TAPS, Crystal Barrel, and Crystal Ball calorimeters. It is motivated as a detailed study of the in-medium properties of hadrons and the meson nucleus interactions. Typical examples for the in-medium behavior of vector mesons (ω), scalar mesons (σ), and nucleon resonances (P33(1232), S11(1535), D15(1520)) are discussed. Special attention is paid to meson nucleus final state interactions.

Hypercentral Constituent Quark Model and Isospin for the Baryon Static Properties
So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent potentials. Here constituent quarks interact with each other via a potential in which we have ta...
متن کاملSelected topics on Hadrons in Nuclei
In this talk we report on selected topics on hadrons in nuclei. The first topic is the renormalization of the width of the Λ(1520) in a nuclear medium. This is followed by a short update of the situation of the ω in the medium. The investigation of the properties of K̄ in the nuclear medium from the study of the (Kflight, p) reaction is also addressed, as well as properties of X,Y,Z charmed and ...
متن کاملHadron spectrum and hadrons in the nuclear medium
Some recent developments in chiral dynamics of hadrons and hadrons in a medium are presented. Unitary schemes based on chiral Lagrangians describe some hadronic states as being dynamically generated resonances. We discuss how standard quantum many body techniques can be used to calculate the properties of these dynamically generated and other hadrons in the nuclear medium. We present some resul...
متن کاملImpact of Four-Quark Condensates on In-Medium Effects of Hadrons
Spectral properties of hadrons in nuclear matter are treated in the framework of QCD sum rules. The influence of the ambient strongly interacting medium is encoded in various condensates. Especially, the structure of different four-quark condensates and their density dependencies in light quark systems are exemplified for the ω meson and the nucleon.
متن کاملProbing In-medium Vector Mesons by Dileptons at Heavy-ion Colliders *
An introduction to physics of in-medium hadrons with special emphasis towards modification of vector meson properties in dense nuclear matter is given. We start from remarkable analogy between the in-medium behavior of atoms in gases and hadrons in nuclear matter. Modifications of vector meson widths and masses can be registered experimentally in heavy-ion collisions by detecting dilepton spect...
