Chiral dynamics of hadrons in nuclei
In this talk I report on selected topics of hadron modification in the
nuclear medium using the chiral unitary approach to describe the dynamics of
the problems. I shall mention how antikaons, , and are modified in
the medium and will report upon different experiments done or planned to
measure the width in the medium.Comment: 10 pgs, 3 figs. Invited talk in the Workshop on in Medium Hadron

Recent developments in chiral dynamics of hadrons and hadrons in nuclei
In this talk I present recent developments in the field of hadronic physics
and hadrons in the nuclear medium. I review the unitary chiral approach to
meson baryon interaction and address the topics of the two dynamically
generated resonances, with experiments testing it, the
and resonances, plus the ,
and in the nuclear medium.Comment: 9 pages, 8 figures, Talk at YKIS06 Kyoto Symposium, Kyoto, december

Chiral dynamics of baryon resonances and hadrons in a nuclear medium
In these lectures I make an introduction to chiral unitary theory applied to
the meson baryon interaction and show how several well known resonances are
dynamically generated, and others are predicted. Two very recent experiments
are analyzed, one of them showing the existence of two
states and the other one providing support for the
resonance as a quasibound state of . The
use of chiral Lagrangians to account for the hadronic interaction at the
elementary level introduces a new approach to deal with the modification of
meson and baryon properties in a nuclear medium. Examples of it for ,
and modification in the nuclear medium are presented.Comment: Lectures given in the Workshop on Hadron Physics, Puri (India), march

Baryon Resonances
In this talk I show recent results on how many excited baryon resonances
appear as systems of one meson and one baryon, or two mesons and one baryon,
with the mesons being either pseudoscalar or vectors. Connection with
experiment is made including a discussion on old predictions and recent results
for the photoproduction of the resonance, as well as the
prediction of one baryon state around 1920 MeV which might have been
seen in the reaction.Comment: Talk given at the 10th International Conference on Hypernuclear and
