Insights and Puzzles in Light Quark Physics
Recent work in light flavour hadron physics is reviewed. In particular, I discuss the significance of the progress achieved with light dynamical quarks on the lattice for the effective low energy theory of QCD. Also, I draw attention to some puzzling results from NA48 and KTeV concerning the scalar form factor relevant for Kμ3 decay – taken at face value, these indicate physics beyond the Stand...
متن کاملThe Hydra genome: insights, puzzles and opportunities for developmental biologists.
The sequencing of a Hydra genome marked the beginning of a new era in the use of Hydra as a developmental model. Analysis of the genome sequence has led to a number of interesting findings, has required revisiting of previous work, and most importantly presents new opportunities for understanding the developmental biology of Hydra. This review will de-scribe the history of the Hydra genome proj...
متن کاملThe Thermodynamic Arrow: Puzzles and Pseudo-puzzles
For more than a century, physics has known of a puzzling conflict between the T-asymmetry of thermodynamic phenomena and the T-symmetry of the underlying microphysics on which these phenomena depend. This paper provides a guide to the current status of this puzzle, distinguishing the central issue from various issues with which it may be confused. It is shown that there are two competing concep...
متن کاملMachine-Made Puzzles and Hand-Made Puzzles
Originally puzzles were not for recreation, but serious questions you might be killed if you couldn’t solve them. But in modern times, puzzles had become a sort of recreation, decreasing the seriousness and religiousness gradually. Now, the ‘rule creators’ of puzzles began to attract notice. I, as a rule creator, published a book, Kyoto University Student, Higashida’s Puzzles. I’ll show several...
متن کاملInsights and Puzzles from Branes: 4d SUSY Yang-Mills from 6d Models
5-branes of nontrivial topology are associated in the Diaconescu-Hanany-Witten-Witten (DHWW) approach with the Seiberg-Witten (SW) theory of low-energy effective actions. There are two different ”pictures”, related to the IIA and IIB phases of M -theory. They differ by the choice of 6d theory on the 5-brane world volume. In the IIB picture it is just the 6d SUSY Yang-Mills, while in the IIA pic...
