The multiplicities of charged secondaries in proton-proton collisions were determined using the split-field-magnet detector at CERN Intersecting Storage Rings (ISR). Measurements are presented on multiplicity distributions both for inelastic and non-single-diffractive events four different energies $\sqrt{s}=30.4, 44.5, 52.6, \mathrm{and} 62.2$ GeV. results reported here represent first high-statistics measurement ISR with a magnetic covering nearly full solid angle.
We have measured the differential cross section for $\overline{p}p$ and $\mathrm{pp}$ elastic scattering at $\sqrt{s}=53$ GeV in interval $0.5<|t|<4.0$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$ CERN intersecting storage rings using split-field magnet detector. The shape of differs significantly between region $1.1<|t|<1.5$ ${(\mathrm{G}\mathrm{e}\mathrm{V}/\mathit{c})}^{2}$, with data showing a less pronounced dip structure than data.
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...
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.
Single photons detected by the DELPHI experiment at LEP2 in years 1997–2000 are reanalysed to investigate existence of a single extra dimension modified ADD scenario with slightly warped large dimensions. The data collected centre-of-mass energies between 180 and 209 GeV for an integrated luminosity ∼650 pb−1 agree predictions Standard Model allow limit be set on graviton emission one dimension. obtained fundamental mass scale M D is 1.69 TeV/c 2 95% CL, expected 1.71 2.
The ${\ensuremath{\Sigma}}^{+}$ magnetic moment is measured to be $(2.38\ifmmode\pm\else\textpm\fi{}0.02){\ensuremath{\mu}}_{N}$ with use of 44 457 polarized ${\ensuremath{\Sigma}}^{+}\ensuremath{\rightarrow}p{\ensuremath{\pi}}^{0}$ decays in a charged hyperon beam. inclusively produced this 210-GeV/c beam have polarization about 0.20 for production angles between 2.5 and 7.0 mrad.
A search for single top production (e+e−→tc̄) via flavour changing neutral currents (FCNC) was performed using the data taken by DELPHI detector at LEP2. The analyzed have been accumulated center-of-mass energies ranging from 189 to 208 GeV. Limits 95% confidence level were obtained on anomalous coupling parameters κγ and κZ.
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...
