Introduction: Radiotherapy with heavy charged particles such as protons and carbon ions (hadron therapy) has been recognized as an advanced technique for the treatment of various cancers. For some indications such as pediatric and radio-resistant tumors, it is considered the preferred method. However, despite its remarkable benefits, development of hadron therapy centers in the...

One of the most interesting consequence of non-zero intrinsic transverse momentum of partons in the nucleon is the nontrivial azimuthal dependence of the cross section of hard scattering processes. Many of the observable asymmetries contain unknown functions which provide essential information on the quark and gluon structure. Several of them have been studied in the last few years; we discuss ...

Understanding the spin structure of proton is large interest to nuclear physics community and it one main goals program at Relativistic Heavy Ion Collider (RHIC). Measurements from data taken by PHENIX detector with transverse (p ↑ + p, p Al, Au) longitudinal (⃗p ⃗p) polarization play an important role in this, particular due leading order access gluons polarized protons. This a crucially counter...

Top quark pairs are produced with strongly correlated spins in the partonic reactions qq̄ → tt̄ and gg → tt̄. A complete description of these effects in terms of the spin density matrix of the tt̄ system in leading order QCD is given. We further discuss the prospects to observe the spin-spin correlations at pp̄ and pp colliders by measuring suitable angular correlations among the t and t̄ decay produ...

The J-PARC facility is near completion and experiments will start in 2009 on nuclear and particle physics projects. In this article, the J-PARC facility is introduced, and possible projects are discussed in high-energy hadron physics by using the primary proton beam of 30−50 GeV. There are proposed experiments on charm-production and Drell-Yan processes as well as single spin asymmetries for in...

The strong coupling constants of hadronic multiplets are fundamental parameters which carry information about the interactions among participating particles. These can help us construct hadron-hadron potential and gain structure involved hadrons. Motivated by recent observation doubly charmed state LHCb, we determine heavy spin-1/2 baryons, , light pseudoscalar mesons, K, within framework cone ...
