Abstract:We have calculated the electroweak O(α) corrections to the processes pp → Zγ + X → ν lνl γ + X, pp → Zγ + X → llγ + X, and pp → Wγ + X → ν ll γ + X at the LHC, with l = e, µ and ν l = ν e , ν µ , ν τ . The virtual corrections are evaluated in leading-pole approximation, whereas the real corrections are taken into account exactly. These corrections are implemented into a Monte Carlo generator which includes both phase-space slicing and subtraction to deal with soft and collinear singularities. We present numerical results for total cross sections as well as for experimentally interesting distributions. Applying typical LHC cuts, the electroweak corrections are of the order of −5% for the total cross sections and exceed −20% for observables dominated by high centre-of-mass energies of the partonic processes.

In this paper we present the results from a calculation of the full electroweak oneloop corrections for γZ vector-boson pair production at hadron colliders. The cases of proton-antiproton as well as proton-proton collisions, at the Tevatron and the LHC, respectively, are considered. Results are presented for the distribution of the γZ invariant mass and for the transverse momentum of the final-state photon. The higher-order electroweak effects are numerically significant, in particular for probing possible anomalous gauge-boson couplings.

Lead (Pb) is a ubiquitous poisonous metal, affecting the health of vast populations worldwide. Medications to treat Pb poisoning suffer from various limitations and are often toxic owing to insufficient metal selectivity. Here, we report a cyclic tetrapeptide that selectively binds Pb and eradicates its toxic effect on the cellular level, with superior potency than state‐of‐the‐art drugs. The Pb‐peptide complex is remarkably strong and was characterized experimentally and computationally. Accompanied by the lack of toxicity and enhanced stability of this peptide, these qualities indicate its merit as a potential remedy for Pb poisoning.

We have analyzed the most recent available Super-Kamiokande data in a three flavor neutrino oscillation model. We have here neglected possible matter effects and performed a fit to atmospheric and solar Super-Kamiokande data. We have investigated a large parameter range, where the mixing angles were restricted to 0 ≤ θi ≤ π/2, i = 1, 2, 3, and the mass squared differences were taken to be in the intervals 10
