Nonstandard Parafermions and String Compactification
Nonstandard Parafermions String Compactification High Energy Physics - Theory
font style='font-size:12px;'>
2011/9/29
Abstract: Nonstandard parafermions are built and their central charges and dimensions are calculated. We then construct new N=2 superconformal field theories by tensoring the parafermions with a free ...

Fractional Action Cosmology Dark Energy Model Emergent Logamediate Intermediate Scenarios of the Universe
font style='font-size:12px;'>
2011/8/2
Abstract: In the framework of Fractional Action Cosmology, we have reconstructed the scalar potentials and scalar fields, namely, quintessence, phantom, tachyon, k-essence, DBI-essence, Hessence, dila...
PT symmetry in relativistic quantum mechanics
PT symmetry relativistic quantum mechanics High Energy Physics - Theory
font style='font-size:12px;'>
2011/9/29
Abstract: In nonrelativistic quantum mechanics and in relativistic quantum field theory, time t is a parameter and thus the time-reversal operator T does not actually reverse the sign of t. However, i...
Did Edwin Hubble plagiarize?
Edwin Hubble plagiarize Lemaitre's earlier theoretical discovery the expansion of the universe
font style='font-size:12px;'>
2011/8/2
Abstract: Recently Block published an astro-ph [arXiv:1106.3928 (2011)] insinuating that Hubble censored a prior publication of his famous and seminal discovery of the expansion of the universe. This ...
Semiclassical Description of Relativistic Spin without use of Grassmann variables and the Dirac equation
Relativistic Spin Grassmann variables Dirac equation
font style='font-size:12px;'>
2011/9/29
Abstract: We propose the relativistic particle model without Grassmann variables which, being canonically quantized, leads to the Dirac equation. Both $\Gamma$\,-matrices and the relativistic spin-ten...
Steady-State Neutronic Analysis of Converting the UK CONSORT Reactor for ADS Experiments
ADS Neutronics Analysis Accelerator Physics
font style='font-size:12px;'>
2011/8/2
Abstract: CONSORT is the UK's last remaining civilian research reactor, and its present core is soon to be removed. This study examines the feasibility of re-using the reactor facility for accelerator...
The UA9 experimental layout
Accelerator Subsystems and Technologies Beam-line instrumentation Instrumentation for particle accelerators and storage rings - high energy.
font style='font-size:12px;'>
2011/9/8
The UA9 experimental equipment was installed in the CERN-SPS in March ’09 with the aim of investigating crystal assisted collimation in coasting mode. Its basic layout comprises silicon bent crystals ...
Computing trends using graphic processor in high energy physics
gpu high energy physics trend overview
font style='font-size:12px;'>
2011/9/29
One of the main challenges in Heavy Energy Physics is to make fast analysis of high amount of experimental and simulated data. At LHC-CERN one p-p event is approximate 1 Mb in size. The time taken to ...
