Amplitude Analysis in Hadron Spectroscopy

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

Dr. Cesar Fernandez Ramirez Jefferson lab


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.


Dr. César Fernández-Ramírez is a postdoctoral researcher at the Center for Theoretical and Computational Physics at Thomas Jefferson National Accelerator Facility (Jefferson Lab, Newport News, Virginia). He received his Ph. D. in Physics at Universidad Complutense de Madrid (Spain) in 2006 and has been postdoctoral researcher at Massachusetts Institute of Technology (Cambridge MA), European Centre for Theoretical Studies in Nuclear Physics and Related Areas (ECT*, Trento, Italy) and Universidad Complutense de Madrid (Spain). He is a member of the Joint Jefferson Lab/Indiana University Physics Analysis Center devoted to provide amplitude analysis for experimental collaborations in nuclear and particle physics at facilities such as Jefferson Lab (USA), MAMI (Mainz, Germany), PANDA (Darmstadt, Germany), LHCb (CERN, Switzerland) and COMPASS (CERN, Switzerland).


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


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.


Bingqian Xu is an Associate Professor of College Engineering and holds Adjunct Professor of Chemistry and Physics in The University of Georgia (UGA). He received his Ph. D. in Materials Science and Engineering at Arizona State University (ASU) in 2004 and worked as a Faculty Research Associate in ASU until he came to UGA in 2006. His BS degree in Physics and Geography was offered by Northwestern University, Xian, China. He taught Quantum Physics in China until he came to the US in 2000 and cofounded a company orthokeratology. Presently, his main research interests are in molecular nanoelectronics, nanobiotechnology and single molecule techniques and pioneers in SPM-based single molecule study techniques. He published over 70 research papers in journals of Science, PNAS, JACS, Nano letters, Small, Angew Chem., etc. He is a member of American Physical Society, American Chemical Society and Materials Research Society.
