With the completion of 7 TeV and 8 TeV data taking at the Large Hadron Collider (LHC), the physics community witnessed one of the great triumphs of modern physics: the completion of the Standard Model (SM) as an effective theory. The final missing particle, the Higgs boson, was observed and its mass was measured. However, many theoretical questions remain unanswered. What is the source of elect...

The linear k⊥-factorization is part and parcel of the pQCD description of high energy hard processes off free nucleons. In the case of heavy nuclear targets the very concept of nuclear parton density becomes ill-defined as exemplified by the recent derivation [2] of nonlinear nuclear k⊥-factorization for forward dijet production in DIS off nuclei. Here we report a derivation of the related brea...

Abstract To study the effect of off-axis initiation on shaped charge performance. The nonlinear finite element software LS-DYNA is used to simulate jet forming and armour-breaking process under different offsets (0.025~0.125D k , D diameter). A theoretical model established analyse lateral velocity distribution jet. results show that degree asymmetric collapse increase with offset. When offset ...

Title of dissertation: Physics of Breaking Bow Waves: A Parametric Investigation using a 2D+T Wave Maker Eric Maxeiner, Doctor of Philosophy, 2009 Dissertation directed by: Professor James H. Duncan Department of Mechanical Engineering A mechanical 2-dimensional wave maker with a flexible surface was used to create waves similar to those formed at the bow of a moving ship. Utilizing the 2D+T ap...

In this talk we discuss recent progress concerning precise predictions for the LHC. We give a status report of an application of the GOLEM method to deal with multi-leg one-loop amplitudes, namely the next-to-leading order QCD corrections to the process pp → V V + jet, where V is a weak boson W ± , Z. The Large Hadron Collider (LHC) at CERN will probe our understanding of electroweak symmetry b...

Whether gamma-ray bursts are highly beamed or not is a very important question, since it has been pointed out that the beaming will lead to a sharp break in the afterglow light curves during the ultra-relativistic phase, with the breaking point determined by Γ ∼ 1/θ 0 , where Γ is the bulk Lorentz factor and θ 0 is the initial half opening angle of the ejecta, and such a break is claimed to be ...

The present work describes the vortex–vortex interactions observed during laboratory experiments, where a single regular water wave is allowed to travel over discontinuous rigid bed promoting generation of both near-bed and surface vortices. While vortices are generated by flow separation occurring at discontinuity, induced breaking in conjunction with breaking-induced jet. A ‘backward breaking...

We show that our recent SU(4) generalized “rishon” composite model for quarks and leptons, augmented either by the hypothesis of breaking of color SU(3) to “glow” SO(3), or by the hypothesis of incomplete color neutralization in very hard processes, leads to an interpretation of the HERA positron-jet events as the production by color gluon exchange, followed by the decay by color gluon emission...

Events with signatures involving large missing transverse energy (E T /) are among the quintessential search modes for R-parity conserving supersymmetry. CDF has conducted two recent analyses for supersymmetry which use E T / and jets. The E T / and monojet signature is employed to determine process independent limits for the production of new physics beyond the Standard Model and then applied ...
