Cross-section measurement of theBa130(p,γ)La131reaction forγ-process nucleosynthesis

Np Cross Section for Big Bang Nucleosynthesis

The total cross sections for the radiative neutron capture on a proton, np → dγ, and its inverse reaction dγ → np are evaluated at the big bang nucleosynthesis (BBN) energies. We employ the effective field theory with dibaryon field to describe the two-nucleon reactions with external electromagnetic probe. Electromagnetic transition amplitudes are obtained up to next-to leading order. Our resul...

Cross Section Measurement at CMS

The startup of the Large Hadron Collider will allow scientists to probe energy scales that existed picoseconds after the Big Bang. Monte Carlo samples of many Standard Model processes are produced to simulate the conditions in the Compact Muon Solenoid detector. Data analysis techniques are developed to measure the cross section of the WZ 3e(e, 1u) decay channel. The results are al = 723.4 + 27...

Jet Cross Section Measurement at Dø

We present a new preliminary measurement of the inclusive jet cross section in p¯ p collisions based on a integrated luminosity of about 0.8 fb −1. The data were acquired using the DØ detector between 2002 and 2005. Jets are reconstructed using an iterative cone algorithm with radius Rcone = 0.7. The inclusive jet cross section is presented as a function of transverse jet momentum and rapidity....

An Upper Bound Solution for Analysis of Twist Extrusion Process with Elliptical Die Cross-section

Twist extrusion process is a rather new route to produce highly strained materials. In this process, severe plastic deformation is applied by large shear strains. In current article, required energy for twist extrusion by use of admissible velocity field together with the upper bound technique is predicted. The proposed model is capable of considering the effect of various parameters such as di...
