[Theory-seminars] Theory seminar tomorrow - Daniel Sadasivan

[Caroline Costa]

Hello All,

Tomorrow, January 31st at 1:00PM (EST), Daniel Sadasivan will give a (virtual) theory seminar on: https://jlab-org.zoomgov.com/j/1611179843?pwd=M09CNTFpbFVZSW1IQlhIMGp3RUVHUT09
Please see below for the title and abstract of Daniel's talk.

Theory Seminar
Monday, January 31st at 1:00PM

Daniel Sadasivan (Ave Maria University)
will speak about the "Pole Position of the a1(1260) with a three-body unitary framework from the infinite and finite volume"

Abstract:
Masses, widths, and branching ratios of hadronic resonances are quantified by their pole positions and residues with respect to transition amplitudes on the Riemann sheets of the complex energy-plane. We calculate three-body scattering amplitudes with integration contours that respect the analytic structure in the physical energy region. Using these amplitudes we determine the pole position of the a1(1260) resonance with both the infinite and finite volume by fitting to data from the ALEPH experiment and Lattice QCD data respectively.

See you tomorrow!
Caroline, Colin & Patrick
