The RBO turns 50 and gets a present

A RBO faz 50 anos e ganha um presente This year, the RBO will be 50 years old! The history of the RBO began in 1965. After a difficult start led by Marcio Ibrain, it was kept going for a long time through the dedication of our dearly missed friend, Donato, who was followed by Giesta. This history has already been narrated in this space. We started our activity in the RBO in 2009, nominated by t...

Functional Proteins from Short Peptides: Dayhoff's Hypothesis Turns 50.

First and foremost: Margaret Dayhoff's 1966 hypothesis on the origin of proteins is now an accepted model for the emergence of large, globular, functional proteins from short, simple peptides. However, the fundamental question of how the first protein(s) emerged still stands. The tools and hypotheses pioneered by Dayhoff, and the over 65 million protein sequences and 12 000 structures known tod...

My 50 years of research in particle physics

Some of my work of the last 50 years in the field of theoretical particle physics is described with particular emphasis on the motivation, the process of investigation, relationship to the work of others, and its impact. My judgment is unavoidably subjective, although I do present the comments of other researchers as much as possible.

P - PH - 9 50 63 16 B Physics : Theoretical Aspects

Some aspects of B physics relevant for experiments in hadron colliders are discussed. These include the determination of parameters of the CKMMatrix and con rmation of its role in CP violation, studies of mixing of nonstrange and strange B mesons, lifetimes of hadrons containing b quarks, the use of \same-side" tagging of neutral B mesons via correlations with charged pions through fragmentatio...
