The nature of b-quark jet hadronisation has been investigated using data taken at the Z peak by DELPHI detector LEP. Two complementary methods are used to reconstruct energy weakly decaying b-hadrons, $E_{\mathrm{B}}^{\mathrm{weak}}$ . average value $x^{\mathrm{weak}}_{\mathrm{B}} = E_{\mathrm{B}}^{\mathrm{weak}}/E_{\mathrm{beam}}$ is measured be 0.699±0.011. resulting $x^{\mathrm{weak}}_{\mathrm{B}}$ distribution then analysed in framework two choices for perturbative contribution (parton...

The advent of artificial intelligence (AI) is reshaping many facets daily life, including education. As AI technologies become more advanced and accessible, their application in teaching learning processes has accelerated. However, systems are frequently designed with politically influenced algorithms that may impact educational content outcomes. This study examines the influence a specific system on Italian grammar. Through qualitative approach, it investigates whether can deliver standard...

The energy resolution of the barrel part CMS Electromagnetic Calorimeter has been studied using electrons 20 to 250 GeV in a test beam. incident electron's was reconstructed by summing measured arrays 3 × or 5 channels. There no significant amount correlated noise observed within these arrays. For at centre crystals, mean stochastic term be 2.8% and constant 0.3%. electrons' which is contained array depends on its position incidence. variation containment with corrected for distribution...

A search for pair-produced doubly charged Higgs bosons has been performed using the data collected by DELPHI detector at LEP centre-of-mass energies between 189 and 209 GeV. No excess is observed in with respect to Standard Model background. lower limit mass of 97.3 GeV/c2 95% confidence level set left–right symmetric models any value Yukawa coupling τ leptons.

Calibration of the relative response individual channels barrel electromagnetic calorimeter CMS detector was accomplished, before installation, with cosmic ray muons and test beams. One fourth exposed to a beam high energy electrons calibration channels, intercalibration, found be reproducible precision about 0.3%. Additionally, data were collected rays for entire ECAL during commissioning phase. By comparing intercalibration constants obtained electron those from data, it is demonstrated...

A determination of the single W spin density matrix (SDM) elements in reaction e+e-→W+W-→lνqq̄(l=e/μ) is reported at centre-of-mass energies between 189 and 209 GeV. The data sample used corresponds to an integrated luminosity 520 pb-1 taken by DELPHI 1998 2000. SDM elements, ρττ' W± (τ,τ'=± 1 or 0), are determined as a function W- production angle with respect e- beam direction obtained from measurements decay products application suitable projection operators, Λττ', which assume V-A...

Inclusive J/psi production in photon-photon collisions has been observed at LEP II beam energies. A clear signal from the reaction gamma -> J/psi+X is seen. The number of N(J/psi mu+mu-) events 36 +/- 7 for an integrated luminosity 617 pb^{-1}, yielding a cross-section sigma(J/psi+X) = 45 9 (stat) 17 (syst) pb.
