Opportunities for high sensitivity charm physics at Fermilab

OSTI OAI (U.S. Department of Energy Office of Scientific and Technical Information) (1996)

The CO initiative under consideration at Fermilab makes feasible a charm experiment reconstructing >10{sup 9} charm decays, four orders - of magnitude beyond the largest extant sample. The experiment might commence data-taking as early as 1999. In addition to programmatic charm physics such as spectroscopy, lifetimes, and QCD tests, it will have significant new-physics reach in the areas of CP violation, flavor-changing neutral-current and lepton-number-violating decays, and D{sup o} {bar D} {bar {sup o}} mixing, and should observe direct CP violation in Cabibbo-suppressed D decays if it occurs at the level predicted by the Standard Model.

Neutral-particle production inπ−pinteractions at 147 GeV/cand comparison to charged-particle production

Physical review. D. Particles, fields, gravitation, and cosmology/Physical review. D. Particles and fields (1979)

D. Brick D. Fong M. Heller A. Shapiro M. Widgoff

The production of ${K}_{S}$, $\ensuremath{\Lambda}$, $\overline{\ensuremath{\Lambda}}$, and $\ensuremath{\gamma}$ in ${\ensuremath{\pi}}^{\ensuremath{-}}p$ collisions at 147 GeV/c is analyzed. Cross sections, rapidity, Feynman-$x$, and ${{p}_{T}}^{2}$ distributions are presented and compared to charged-particle production. The energy dependence of multiplicities in ${\ensuremath{\pi}}^{\ensuremath{-}}p$ and $\mathrm{pp}$ collisions is shown. A new scaling form for the correlation of neutral- and charged-particle multiplicities is presented for compilations of $\ensuremath{\pi}p$ and $\mathrm{pp}$ data.

Study of the decay D0→K−K+π−π+

Physics Letters B (1998)

E. M. Aitala S. Amato J. C. Anjos J. A. Appel D. Ashery

Using data from Fermilab fixed-target experiment E791, we measure the branching ratio for D0→K−K+π−π+ and its resonant components. We find Γ(D0→K−K+π−π+)Γ(D0→K−π+π−π+)=(3.13±0.37±0.36)%. A coherent amplitude analysis is used to estimate the resonant components. We measure the ratios Γ(D0→f)Γ(D0→K−π+π−π+) to be (2.0±0.9±0.8)% for f=φρ0, (0.9±0.4±0.5)% for f=φπ+π−, <2.0% at the 90% CL for f=K∗0(892)K∗0(892), and <1.0% at the 90% CL for f=K∗0(892)K+π− or K∗0(892)K−π+.
