We review the status of QCD at hadron colliders with emphasis on precision predictions and the latest theoretical developments for cross sections calculations to higher orders. We include an overview of our current information on parton distributions and discuss various Standard Model reactions such as W±/Z-boson, Higgs boson or top quark production.

We present a picture of confinement based on representation of quarks as pointlike topological defects. The topological charge carried by quarks and confined in hadrons is explicitly constructed in terms of Yang-Mills variables. In 2+1 dimensions we are able to construct a local complex scalar field V (x), in terms of which the topological charge is Q = − i 4π d 2 xǫ ij ∂ i (V * ∂ i V − c.c.). ...

introduction use of hadron therapy as an advanced radiotherapy technique is increasing. in this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. in this study, monte carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. materials and methods i...

We review the current status of jet measurements in heavy-ion collisions at Large Hadron Collider (LHC) and Relativistic Heavy Ion (RHIC). discuss how provide information about quark-gluon plasma near future opportunities both RHIC LHC.

QCD has been called the perfect theory [1]; as a renormalizable field theory whose validity could extend up to the grand unification scale, it provides the mechanism for generating nearly all the mass of the visible universe. The current quark masses are the only external parameters in the theory. Quenched QCD, without dynamical quarks, explains the hadron spectrum to an accuracy a of 10%. Thes...
