Recently, it was extracted for the first time from the Lamb shift in muonic hydrogen. For a long time it was anticipated that such a measurement would reduce the error by an order of magnitude compared to measurements from electron- proton scattering and regular hydrogen spectroscopy. While this goal was achieved, the value of the proton's charge radius that was obtained was, very surprisingly, five standard deviations away from the world average.
The extraction of the charge radius from the Lamb shift in muonic hydrogen depends on a theoretical input. Together with Richard J. Hill, we are studying the hadronic uncertainty in the theoretical prediction using the tool of an effective field theory, namely NRQED. In the talk I will describe the results of this study. I will also describe a previous study of the model-independent extraction of the charge radius from electron-proton scattering We have shown that previous extractions, spanning a period of over 40 years, have underestimated their error sometimes by a factor of two or more.

Weizmann InstituteOrganizer Department of Particle Physics and AstrophysicsContact Abstract Show full text abstract about Direct photons are a key probe for understanding the hot den...» Direct photons are a key probe for understanding the hot dense matter created in heavy ion collisions. The signature result of heavy ion experiments thus far, is the dramatic modification of the production of strongly interacting particles in the hot and dense medium. Since the photon does not undergo any strong force interactions, it emerges from the medium unmodified and is a clean probe which can be contrasted to measured jets and strongly interacting particles. In particular, photon-jet correlations have been referred to as a golden channel in heavy ion collisions. In a photon-jet event the unmodified photon allows us a direct insight into the modification of the opposite side jet. The results from RHIC and LHC will be discussed. -

School of Chemistry at Tel-Aviv UniversityOrganizer Department of Molecular Chemistry and Materials ScienceContact Abstract Show full text abstract about Salalens are tetradentate dianionic sequential {ONN'O}-...» Salalens are tetradentate dianionic sequential {ONN'O}-type ligands that lead to octahedral complexes of group 4 metals of the type [{ONN'O}MX2] of fac-mer geometry and C1-symmetry. We have recently developed an efficient methodology for the synthesis of Salalen ligands that enables the fine-tuning of steric and electronic parameters. We found that several titanium complexes of these ligands led to highly active catalysts for polymerization of alpha-olefins, and, most importantly, to polypropylene with very high isotacticities, reaching [mmmm] > 99.6% and melting transitions of up to 169.9 °C, which is unprecedented, to our knowledge. In this presentation we will describe the design principles that have led to this development, and, as time allows, the development of other homogeneous catalysts for stereoregular polymerization. -

A minimal dynamical model that reproduces the statistical features of experimental trajectories, is deduced from trajectory data. This model extends the cell-type specific models derived for mammalian cells a few years ago.
