A Study of Charged Pseudoscalar Meson Photoproduction From Hydrogen and Deuterium With 16-{GeV} Linearly Polarized Photons

Quinn, D.J. ; Rutherfoord, J.P. ; Shupe, M.A. ; et al.

Phys.Rev.D 20 (1979) 1553, 1979.

Inspire Record 140543 DOI 10.17182/hepdata.24208

The asymmetries in forward π−N, π−Δ, and K+−(Λ+Σ) photoproduction have been measured with a 16-GeV linearly polarized beam. The experimental method and the procedures for extracting cross sections and asymmetries from the data are discussed in detail. Information on the energy and momentum-transfer dependence of cross sections for natural- and unnatural-parity exchange, interference between exchanges of opposite G parity, and vector-meson dominance is obtained and discussed.

Inclusive Production of $D$ and $K$ Mesons in $e^+ e^-$ Annihilation

Piccolo, M. ; Peruzzi, I. ; Rapidis, P.A. ; et al.

Phys.Lett.B 86 (1979) 220-224, 1979.

Inspire Record 141018 DOI 10.17182/hepdata.27301

We present measurements of the cross section for inclusive D and K meson production in e + e − annihilation in the center of mass energy range 3.6 to 5.8 GeV. D production accounts for most of the increase in the total cross section for hadron production in e + e − annihilation at energies above 4 GeV.

Channel Cross-sections and Two-body Reactions in $K^- p$ Interactions at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Givernaud, A. ; Denegri, D. ; Lewin, C. ; et al.

Nucl.Phys.B 160 (1979) 445-466, 1979.

Inspire Record 141995 DOI 10.17182/hepdata.34613

We present a systematic investigation of channel cross sections in K − p interactions at 32 GeV/ c . The energy dependence of these cross sections is discussed. We also investigate a few non-diffractive two-body reactions. The total cross sections of the two reactions K − p → K ∗− (890) p and K − p → K ∗− (1420) p have a markedly different energy behaviour. There is clear evidence for the reaction K − p → K ∗0 (890) N 0 (1688) ; its differnttial cross section exhibits a sharp forward slope of 24 ± 3 GeV −2 .

Measurements of Elastic Rho and Phi Meson Photoproduction Cross-Sections on Protons from 30 GeV to 180 GeV

Egloff, R.M. ; Davis, P.J. ; Luste, G. ; et al.

Phys.Rev.Lett. 43 (1979) 657, 1979.

Inspire Record 141059 DOI 10.17182/hepdata.20740

The elastic photoproduction cross sections for ρ and ϕ mesons from protons have been measured from 30 to 180 GeV. The energy dependences agree well with predictions made by using vector-meson dominance and an additive quark model. The ρ cross section is approximately constant with energy while the ϕ cross section rises from 0.5 to 0.7 μb with increasing energy.

Inclusive $\pi^0$ Electroproduction in the Deep Inelastic Region

McPharlin, T.P. ; Caldwell, David O. ; Cumalat, John P. ; et al.

Phys.Lett.B 90 (1980) 479-484, 1980.

Inspire Record 143042 DOI 10.17182/hepdata.27245

Using 20.5 GeV electrons on protons, we measured inclusive π 0 's (of transverse momentum, p T , from 0 to 1.4 GeV/ c ) produced by virtual photons of energy, ν, from 4 to 16.5 GeV and four-momentum squared, q 2 , from −1.8 to −8.5 (GeV/ c ) 2 . Comparing with charged pion data, we find σ π 0 = 1 2 (σ π + + σ π − ) , supporting the quark model. Photon knockout of a quark is favored as the interpretation of these data because of scaling in z = E π / ν and similarity in z -dependence of other pion production data. Consistent with this interpretation are the dependence of 〈 p T 〉 on q 2 , the azimuthal dependence, and fits to the constituent interchange model. We also observe a possible p T −4 dependence at large | q 2 | over a limited p T range.
