Top quark production in the forward region in proton-proton collisions is observed for the first time. The W+b final state with W→μν is reconstructed using muons with a transverse momentum, p_{T}, larger than 25 GeV in the pseudorapidity range 2.0<η<4.5. The b jets are required to have 50<p_{T}<100 GeV and 2.2<η<4.2, while the transverse component of the sum of the muon and b-jet momenta must ...
For a proper theoretical description of the top quark pair production cross section at the First Muon Collider in the kinematic regime away from the threshold the complete mass and energy dependence has to be taken into account. Two-loop calculations for the photon mediated total cross section are reviewed. For experiments at the Z pole quark mass effects in the total hadronic cross section σ(e...
This paper examines efficient predictive broadcoverage parsing without dynamic programming. In contrast to bottom-up methods, depth-first top-down parsing produces partial parses that are fully connected trees spanning the entire left context, from which any kind of non-local dependency or partial semantic interpretation can in principle be read. We contrast two predictive parsing approaches, t...
We show that Lie group analysis yields the first integrals admitted by any system of ordinary differential equations if the method developed by Nucci (J.) is applied. As an example, we obtain the famous first integral of the Kowalevsky top.
