VII HADRON PHYSICS - 2000
Foreword
The workshop VII Hadron Physics - 2000 was part of a regular se
quence of workshops held since 1988, in different locations within Brazil, de
voted to the study of hadron structure and hadronic reactions.
The meeting took place between 10 and 15 of April 2000, by the sunny
sands of the Tabatinga beach, in the town of Caraguatatuba, State of Sao
Paulo. It was dedicated to Professor Erasmo Madureira Ferreira, in the
year of his seventieth birthday, as a small tribute from our community to his
outstanding role in fostering Hadron Physics in Brazil.
Nowadays, the understanding of the effects of quarks and gluons on static
properties of hadrons and their reactions requires either lattice calculations or
the use of models, since one has to deal with QCD in the confining regime. The
four series of lectures delivered at the workshop by Stanley Brodsky, Barry
Holstein, Dmitri Kharzeev and Otto Nachtmann, provided an updated and
pedagogical account of recent developments in the field of non-perturbative
methods. The content of these lectures is reproduced in this book, which also
includes material presented as seminars and contributed papers.
The organizers and participants of the VII Hadron Physics - 2000
would like to acknowledge the sponsorship and support from several organi
zations. Among the Brazilian sources, we thank Conselho Nacional de De-
senvolvimento Cientffico e Tecnologico (CNPq), Coordenagao para o Aper-
feigoamento do Pessoal Superior (CAPES), Fundagao de Apoio a Pesquisa do
Estado de Sao Paulo (FAPESP), Fundacao de Apoio a Pesquisa do Estado do
Rio de Janeiro (FAPERJ), Fundagao de Apoio a Pesquisa do Estado do Rio
Grande do Sul (FAPERGS) and Universidade de Sao Paulo (CCINT, Pro - Re-
itoria de pesquisa, Pro - Reitoria de pos - graduagao). We are also grateful for
the contributions provided by International Agencies, especially the Interna
tional Centre for Theoretical Physics (ICTP) and the Latin American Center
for Physics (CLAF).
We hope that readers may enjoy this book as we did in attending the
workshop.
