Amplitude Analysis in Hadron Spectroscopy

Jan. 30, 2015, 1:30pm-2:30pm, AHC3 214

Dr. Cesar Fernandez Ramirez Jefferson lab

Abstract

The comprehensive understanding of the strong interaction in the hadronic energy range is one of the open problems in particle and nuclear physics. Problems such as how quarks and gluons aggregate to constitute hadrons, hadrons spectroscopy, the role of chiral symmetry breaking, and confinement have triggered a huge experimental and theoretical effort which is exemplified by the amount of resources poured into this field in the form of experimental facilities (i.e. Jefferson Lab, COMPASS@CERN, LHCb@CERN, PANDA@FAIR, MAMI@Mainz) starting an exciting period in hadron spectroscopy. Besides, Electron-positron collider experiments BaBar and Belle have produced unexpected surprises in the heavy flavor sector, while data on hadron targets of unprecedented statistics have been taken in experiments at CERN by COMPASS and LHCb allowing a search for smaller signals for long sought light and heavy resonances. The analysis of these data requires theoretical input in the form of amplitudes that describe the reactions and allow to extract said resonances (which show up as poles in unphysical Riemann sheets). In this colloquium I will show some of the techniques employed in amplitude analysis and examples on the ongoing program at the Joint Jefferson Lab/Indiana University Physics Analysis Center to provide such amplitudes to the experimental collaborations.

Driving to Contacts: Single Molecular Electronics and Mechanics

Jan. 23, 2015, 1:30pm-2:3pm, GC 280

Dr. Bingqian Xu College of Engineering, University of Georgia

Abstract

Single molecule study, where science and engineering met, applies the tools and measurement techniques of nanoscale physics and chemistry to generate remarkable new insights into how physical, chemical, and biological systems function. It permits direct observation of molecular behavior that can be obscured by ensemble averaging and enables the study of important problems ranging from the fundamental physics of electronic transport in single molecule junctions and biophysics of single molecule interactions, such as the energetics and non-equilibrium transport mechanisms in single molecule junctions and the energy landscape of biomolecular reactions, associated lifetimes, and free energy, to the study and design of single molecules as devices-molecular wires, rectifiers and transistors and high‐affinity, anti‐cancer drugs. I will describe our pioneered highly integrated SPM-based approaches to (1) simultaneously fabricate, control, modulate, and monitor the electronic and mechanical properties of molecular junction devices at the single-molecule level. (2) Probe the biophysical mechanism of single‐molecule interactions, including the binding affinity and specificity. Our recent research examples will be used in the discussions.
