[Theory-seminars] Seminars next week

[Carlota Andres Casas]

Dear all,

Here is a reminder for the seminars next week.

Theory seminar
Monday, Jan 13, 1:00PM, Room L102
Joseph A. Carlson (LANL), "Quantum Monte Carlo Approaches to Electron and Neutrino Scattering from Nuclei"

Abstract:
Electron and neutrinos provide important probes of nuclear structure and dynamics at momenta
corresponding to the inter-nucleon spacing in the nucleus.  Developing a comprehensive understanding
of scattering is becoming more important as a tool to understand neutrino physics, including mixings and
particularly CP violation, and for understanding the short-range structure of nuclei.
It has been known for some time that both two-nucleon correlations and currents are important to
describe this scattering.  I will highlight results from Quantum Monte Carlo approaches that naturally
incorporate both elements, including Green’s function Monte Carlo, Auxiliary Field Diffusion Monte Carlo
and the short-time approximation. The later naturally connects with semi-classical generators often
used in experimental analysis.  I will also describe important problems to be addressed and the future outlook. In particularly quantum scattering at relatively high momenta  is also an early application of quantum computing.

Cake seminar
Wednesday, Jan 15, 1:00PM, Room F324-325
Ishara Fernando (JLab & Hampton U.), "Sigma terms and currents in SU(3) BChPT × 1/Nc"
Abstract:
Baryon Chiral Perturbation Theory (BChPT) and the 1/Nc expansion provide systematic frameworks for the strong interactions at low energy. A combined framework of both expansions has been developed and applied for baryons with three light-quark flavors. The small scale expansion of the combined approach is identified as the ξ-expansion, in which the power counting of the expansions is linked according to O(p) = O(1/Nc) = O(ξ). Results obtained from applying the combined framework to baryon masses, sigma terms and vector and axial-vector currents in SU(3) will be discussed.
