Physics of the light quarks
These lecture notes concern recent developments in our understanding of the low energy properties of QCD. Significant progress has been made on the lattice and the beautiful experimental results on the K e4 and K 3π decays, as well as those on pionic atoms also confirm the results obtained on the basis of Chiral Perturbation Theory. There is an exception: one of the precision experiments on K µ...
متن کاملPhysics at the Light-Front
The light-front representation of quantum chromodynamics provides a frame-independent, quantum-mechanical representation of hadrons at the amplitude level, capable of encoding their multi-quark, hidden-color and gluon momentum, helicity, and flavor correlations in the form of universal process-independent hadron wavefunctions. The universality and frame-independence of the LCWF’s thus allow a p...
متن کاملExtreme Light Infrastructure – Nuclear Physics
The Extreme Light Infrastructure (ELI) is an ESFRI-listed distributed facility that entered the implementation phase. The Romanian pillar will focus on the field of nuclear physics research, performed with the help of an ultra-short-pulse, multi-petawatt scale laser system and a brilliant, tuneable and highly collimated gamma beam system. ELI-Nuclear Physics, an open-access facility, shall beco...
متن کاملThe physics of light and sunlight.
The physical properties of light, both natural and artificial, play a significant role in its interaction with humans. Although there is a yet-to-be-explained duality between light as waves and light as photons, we do understand many of the characteristics of light that affect living things. Here I review the general history of light and its properties, especially those that affect human health.
متن کاملNegative S and Light New Physics *
The several sigma difference between SLD's recent precise measurement of A LR and the corresponding LEP results tends to reinforce the earlier trends in the data towards negative values for the Peskin-Takeuchi parameter S and T. Motivated by this not yet statistically significant, but suggestive, trend, we explore which kinds of new particles can (1) contribute dominantly to new physics through...
