Quantum entanglement between the two $W$ bosons resulting from decay of a Higgs boson may be investigated in dilepton channel $H\ensuremath{\rightarrow}WW\ensuremath{\rightarrow}\ensuremath{\ell}\ensuremath{\nu}\ensuremath{\ell}\ensuremath{\nu}$ using laboratory-frame observables that only involve charged leptons $\ensuremath{\ell}=e$, $\ensuremath{\mu}$. The invariant mass distribution, alread...

Surveillance for mercury (Hg), lead (Pb) and cadmium (Cd) contamination in tuna products is crucial for consumer food safety. Hg, Pb and Cd contaminants were monitored in a total of 60 specimens of fresh little tunny (Euthynnus alletteratus) and popular brands of skipjack and yellowfin (Katsuwonus pelamis and Thunnus albacares) canned tuna commercially available in Tripoli, Libya. Direct Mercur...

Closed-form dynamic stiffness (DS) formulations coupled with an efficient eigen-solution technique are proposed for exact longitudinal free vibration analyses of rods and trusses by using classical, Rayleigh-Love, Rayleigh-Bishop Mindlin–Hermann theories. First, the general solutions governing differential equations four rod theories developed. Then substituted into generalized displacement for...

Concentrations of As, Cu, Fe, Hg, Pb and Zn and activity concentrations from 234,238U and 210Po in water, fillet, liver and gills were determined in three stocked fish species from the Luis L. Leon reservoir, located in Northern Mexico. The considered species were Lepomis cyanellus, Cyprinus carpio and Ictalurus furcatus. 238U and 234U activity concentration (AC) in fillet samples showed values...

This letter reports the observation of photon-induced production W-boson pairs, γγ→WW. The analysis uses 139 fb−1 LHC proton–proton collision data taken at s=13 TeV recorded by ATLAS experiment during years 2015–2018. measurement is performed selecting one electron and muon, corresponding to decay diboson system as WW→e±νμ∓ν final state. background-only hypothesis rejected with a significance w...

Background: Prompt gamma neutron activation analysis (PGNAA) is known as a non-invasive technique capable of measuring elemental concentration in voluminous samples in a short period of time. Also it is a valuable diagnostic tool for total body elemental measurements. 252Cf and 241Am-Be sources which are usually used in this method, generate not only neutrons, but also emit high-energy and unwa...
