Since 2004, the MAGIC γ-ray telescope has newly discovered 6 TeV blazars. The total set of 13 MAGIC-detected active galactic nuclei includes well-studied objects at other wavelengths like Markarian 501 and the giant radio galaxy M 87, but also the distant the flat-spectrum radio quasar 3C 279, and the newly discovered TeV γ-ray emitter S5 0716+71. In addition, also long-term and multi-wavelengt...
We present the final combinations of CDF and D0 measurements of the cross section for single-top-quark production in proton-antiproton collisions at a center-of-mass energy of 1.96 TeV. The data correspond to total integrated luminosities of up to 9.7 fb per experiment. The t-channel cross section is measured to be σt = 2.25 +0.29 −0.31 pb. We also present the simultaneously measured sand t-cha...
A calculation of the total cross section for top quark production in hadronhadron collisions is presented based on an all-orders perturbative resummation of initial-state gluon radiative contributions to the basic quantum chromodynamics subprocesses. Principal-value resummation is used to evaluate all relevant large threshold contributions. In this method there are no arbitrary infrared cutoffs...
Experimental bioinformatics data obtained from an E. coli cell-based eukaryotic protein purification experiment were analyzed in order to identify any bottleneck as well as the factors affecting the target purification. All targets were expressed as His-tagged maltose-binding protein (MBP) fusion constructs and were initially purified by immobilized metal affinity chromatography (IMAC). The tar...
A systematic analysis of transverse momentum and rapidity distributions measured in high-energy proton proton (pp) collisions for energies ranging from 53 GeV to 7 TeV using Tsallis thermodynamics is presented. The excellent description of all transverse momentum spectra obtained in earlier analyses is confirmed and extended. All energies can be described by a single Tsallis temperature of 68 ±...
considering the importance of the agriculture sector in iran, this study investigated factors affecting economic growth and development of the agriculture sector in iran over the period of 1967-2009 for short term and long term, using ardl model. the results showed that the ratios of public investment expenditure to the gdp for short-term and long term have positive impacts on the economic grow...
Distributions of transverse momentum [Formula: see text] and the related angular variable [Formula: see text] of Drell–Yan lepton pairs are measured in 20.3 fb[Formula: see text] of proton–proton collisions at [Formula: see text] TeV with the ATLAS detector at the LHC. Measurements in electron-pair and muon-pair final states are corrected for detector effects and combined. Compared to pre...
In models with TeV-scale gravity it is expected that mini black holes will be produced in nearfuture accelerators. On the other hand, TeV-scale gravity is plagued with many problems like fast proton decay, unacceptably large n − n̄ oscillations, flavor changing neutral currents, large mixing between leptons, etc.. Most of these problems can be solved if different fermions are localized at differ...
considering iran geographical location, water is the most limited factor in agriculture section. therefore, it would be logical to consider water as one of the most significant criteria in selection of cultivation model. the purpose of this study is assigning cultivation pattern based on economic value of water in gotvand township in agronomic year 2008-2009. so it was necessary to computes the...
We report the observation of Higgs boson decays to WW based on an excess over background of 6.1 standard deviations in the dilepton final state, where the Standard Model expectation is 5.8 standard deviations. Evidence for the vector-boson fusion (VBF) production process is obtained with a significance of 3.2 standard deviations. The results are obtained from a data sample corresponding to an i...
