Lectures given at the III Gleb Watagin School, Campinas, July 1994 and at the LAFEX,CBPF, Rio de Janeiro, September 1994, 103 p.
Abstract
These lectures are the review of the main ideas and approaches to the structure of the Pomeron. They are divided in three natural parts:
(i) the brief review of the Reggeon Calculus, which was the first attempt to build the effective theory of the strong interaction at high energy. In spite of the fact that this approach turns out to be inconsistent and in lectures we show why, the Reggeon approach was and is the main source of the terminology and phenomenology for high energy "soft" interactions.
(ii) the detail description of the QCD approach to high energy interaction. We try to combine the rigorous approach in perturbative QCD with more simple, intuitive guess based on general properties of QCD to clarify our expectations and predictions.
(iii) the outline of my personal opinion what problems will be important in the future.
The main reason for the lectures was just the last part to agitate you to think about this difficult but because of that interesting problem. The motto of my lectures is "there is nothing more exciting than to solve a difficult problem. Pomeron is the one."25 years with the Pomeron.
Paper for "Gribov Memorial Volume" , Heavy Ion Physics, Acta Physica Hungarica, August 1998, DESY 98 – 118, 22 p.
Abstract
This paper is written for "Gribov Memorial Volume", Heavy Ion Physics, Acta Physica Hungarica. This is a report on my 25 years activity in understanding of the Pomeron structure. Since I was involved in the Pomeron business moreless from the beginning, I hope, that this report shows the development of the main ideas in their historical perspective from the first enthusiastic attempts to find a simple solution to understanding of the complexity and difficulty of the problem. In other words, this is a story about a young guy who wanted to understand everything in high energy interaction, who did his best but who is still in the beginning, but who has not lost his temper and considers the Pomeron structure as the beautiful and difficult problem, which deserves his time and efforts to be solved.An introduction to Pomerons.
Talk given at Workshop on Diffractivre Physics (Rio de Janeiro, Feb. 1998), 78 p.
Abstract
This talk is an attempt to clarify for experimentalists what we (theorists) mean when we are saying "Pomeron". I hope, that in this talk they will find answers to such questions as what is Pomeron, what we have learned about Pomeron, both experimentally and theoretically, what is correct strategy to study Pomeron experimentally and etc. I also hope that this talk could be used as a guide in the zoo of Pomerons: "soft" Pomeron, "hard" Pomeron, the BFKL Pomeron, the Donnachie-Landshoff Pomeron and so on. The large number of different Pomerons just reflects our poor understanding of high energy asymptotics in out microscopic theory – QCD. The motto of my talk, which gives you my opinion on the subject in short is: "Pomeron is still unknown but needed for 25 year to describe experimental data".
