Charged Particle Multiplicity in Diffractive Deep Inelastic Scattering
The recent data from H1 Collaboration on hadron multiplicity in diffractive DIS has been studied in the framework of perturbative QCD as a function of invariant diffractive mass. The formulas obtained explain the observed excess of particle production in diffractive DIS relative to that in DIS and e+e− annihilation. It is shown that the results are sensitive to the quark–gluon structure of the ...
متن کاملCentrality Dependence of the Charged-Particle Multiplicity Density at Midrapidity
Quantum chromodynamics (QCD), the theory of the strong interaction, predicts a phase transition at high temperature between hadronic and deconfined matter (the quark-gluon plasma). Strongly interacting matter under such extreme conditions can be studied experimentally using ultrarelativistic collisions of heavy nuclei. The field entered a new era in November 2010 when the Large Hadron Collider ...
متن کاملDirect charged-particle measurements with stable beams
A number of examples for direct measurements in nuclear astrophysics are given in order to address several important issues. First, recent results for the 16O(p,γ)17F reaction are discussed and it is shown how an improvement in reaction rate precision allows for significantly improved astrophysical predictions in connection with massive AGB stars. Second, we discuss improved experimental techni...
متن کاملDirect photon-charged particle coincidence measurements in STAR
The multiplicities of charged-particles of 3 < p h ± T < 16 GeV/c and pseudorapidity | η | ≤ 1.0 associated with direct photons and π 0 of 8 < p γ,π 0 T < 16 GeV/c at mid-rapidity | η | ≤ 0.9 have been measured for Au + Au and p + p collisions at √ s NN = 200 GeV in the STAR experiment. A transverse shower-shape analysis in the STAR Barrel Electromagnetic Calorimeter Shower Maximum Detector is ...
متن کاملNa60 Results on Thermal Dimuons Na60 Collaboration
The NA60 experiment at the CERN SPS has measured muon pairs with unprecedented precision in 158A GeV In-In collisions. A strong excess of pairs above the known sources is observed in the whole mass region 0.2<M<2.6 GeV. The mass spectrum for M<1 GeV is consistent with a dominant contribution from ππ → ρ → μμ annihilation. The associated ρ spectral function shows a strong broadening, but essenti...
