In this Letter, we discuss the generation of magnetic field from cosmological perturbations. We consider the evolution of three component plasma (electron, proton, and photon) evaluating the collision term between electrons and photons up to the second order. The collision term is shown to induce electric current, which then generates magnetic field. There are three contributions, two of which ...

These proceedings present a set of PHENIX highlight results using recent high-luminosity data sets for p + , ( d 3 He)+A, and A+A(B) collisions at RHIC top energies with focus on: (1) light-flavor particle productions; (2) hard-probes such as jet-like correlations, direct photon, heavy-quark (3) azimuthal anisotropy in small collision systems.

A summary of the entire scope of the Kansas State University AMO program is contained in the J. R. Macdonald Laboratory abstract. The present document is limited to a discussion of recent progress in the MOTRIMS projects. MOTRIMS, or magneto optical trap recoil ion momentum spectroscopy, is a methodology originally developed for the study of ion-atom or photon-atom collisions. Following the bas...

In the framework of the large extra dimensions (LED) model, the effects of LED on the processes γγ → tt̄h0 and e+e− → tt̄h0 at future linear colliders are investigated in both polarized and unpolarized collision modes. The results show that the virtual Kaluza-Klein (KK) graviton exchange can significantly modify the standard model expectations for these processes with certain polarizations of ini...

Introduction: Previous studies have shown that a Monte Carlo method for the transportations photon beam in medical linear accelerator is a good way. Strip of simulation can be used to measure the dose distribution in phantoms and patients' body. EGSnrc Code is the only code written for use in the field of radiation therapy that has many subset codes that BEAMnrc code is an impo...

The extension of the factorization theorems of perturbative QCD to power corrections associated with re-scattering in nuclear collisions is reviewed. The importance of hadron-nucleus collisions is discussed. Perturbative QCD (pQCD) has been very successful in interpreting and predicting hadronic scattering processes in high energy collisions, even though the physics associated with individual h...

The virtual photon structure function g 1 (x,Q , P ), which can be obtained in polarized ee colliding-beam experiments, is investigated for Λ ≪ P 2 ≪ Q, where −Q (−P ) is the mass squared of the probe (target) photon. The analysis is made to next-to-leading order in QCD, in the framework of the QCD improved parton model with the DGLAP evolution equations. The non-leading corrections significant...

The differential cross section of coherent photo-production heavy quarkonia on nuclear targets is calculated within the QCD color dipole formalism. higher-twist shadowing corresponding to $\bar QQ$ Fock component photon, including correlation between orientation $\vec r$ and impact parameter a collision b$, which related transverse momentum transfer via Fourier transform. We also included leadi...
