Dear All, 

Here is a reminder of the seminar tomorrow at 1pm in room F326-327:

Cake Seminar:
Wednesday, November 14th, 1PM, Room F326-327
Colin Egerer (W&M),"Distillation in Lattice QCD Calculations of Nucleon Isovector Charges g_S, g_A, g_T"

Abstract: 
Reliable calculations in Lattice QCD must confront excited-state contamination and statistical precision, where attempts to reduce excited-state effects are often handled with various "smearing" algorithms. Distillation, a particularly powerful form of smearing has seen extensive use in spectroscopy calculations, yet, until now, has not seen use in calculations of hadronic structure. We investigate the application of the distillation smearing approach, and the use of the variational method with an extended basis of operators facilitated by this approach, in the calculation of the scalar, axial and tensor isovector charges of the nucleon. Quantitative comparisons are made with conventional smearing approaches.

Thank you.

Carlota, Vincent & Raza
