Shielding Experiments Under JASMIN Collaboration at Fermilab(III) - Measurement of High-Energy Neutrons Penetrating a Thick Iron Shield from the Antiproton Production Target by AU Activation Method
JASMIN Collaboration High-Energy Neutrons Thick Iron AU Activation Method
2012/5/17
In an antiproton production (Pbar) target station of the Fermi National Accelerator Laboratory (FNAL), the secondary particles produced by bombarding a target with 120-GeV protons are shielded by a th...
Modified van der Pauw method based on formulas solvable by the Banach fixed point method
van der Pauw method sheet resistance Banach fixed point method cross ratio
2012/4/19
We propose a modification of the standard van der Pauw method for determining the resistivity and Hall coefficient of flat thin samples of arbitrary shape. Considering a different choice of resistance...

Constrained potential method for false vacuum decays
Constrained potential method false vacuum decays
2010/12/27
A procedure is reported for numerical analysis of false vacuum transition in a model with multiple scalar fields. It is a refined version of the approach by Konstandin and Huber. The alteration makes...
A novel method for evaluating correlation functions in lattice hadron spectroscopy
evaluating correlation functions lattice hadron spectroscopy
2011/1/6
We describe a new approach for evaluating hadronic correlation functions which combines Laplacian-Heaviside quark smearing with a stochastic estimator of quark propagators. This method utilizes noise ...
Improved method for calculating nucleon strangeness
Improved method for calculating nucleon strangeness
2011/1/7
The strange quark content of the nucleon, as well as other matrix elements, can be calculated on the lattice by examining correlations between the nucleon propagator and the quark condensate. The larg...

Cosmic Microwave Background Radiation detecting cosmic strings
2010/12/27
In this paper we study the footprint of cosmic string as the topological defects in the very early universe on the cosmic microwave background radiation. We develop the method of level crossing analy...
Pallalel GPGPU computing for lattice QCD simulations has a bottleneck on the GPU to GPU data communication due to the lack of the direct data exchanging facility. In this work we investigate the perfo...
