Unified model of the Hall effect from insulator to overdoped compounds in cuprate superconductors Open
Measurements of the Hall coefficient in La$_{2-x}$Sr$_x$CuO$_4$, ranging from the undoped ($x = p = 0$) Mott insulator to overdoped compounds, exhibit a temperature dependence that offers insights into their electronic structure. We interp…

The role of the pseudogap in cuprate superconductors revealed by the Hall effect Open
Cuprate high-temperature superconductors are known to have a normal-state pseudogap but, after many years of intense research, its relation to the superconductivity is still a mystery. Similarly, the in-plane Hall coefficient $R_{\rm H}$ h…

Measurements of Xi(c)+ branching ratios Open
Using data collected by the fixed target Fermilab experiment FOCUS, we measure the branching ratios of the Cabibbo favored decays $\\Xi_c^+ \\to \\Sigma^+K^-\\pi^+$, $\\Xi_c^+ \\to \\Sigma^+ \\bar{K}^{*}(892)^0$, and $\\Xi_c^+ \\to \\Lambd…

Measurement of the form-factor ratios for D+ ---> anti-K*0 lepton+ lepton-neutrino Open
The form factor ratios rv=V(0)/A1(0), r2=A2(0)/A1(0) and r3=A3(0)/A1(0) in the decay D+ --> K* l nu, K* -->K-pi+ have been measured using data from charm hadroproduction experiment E791 at Fermilab. From 3034 (595) signal (background) even…

Mass splitting and production of sigma(c)0 and sigma(c)++ measured in 500-GeV pi- n interactions Open
>From a sample of $2722 \\pm 78$ $\\Lambda_c~+$ decaying to the $pK~-\\pi~+$ final state, we have observed, in the hadroproduction experiment E791 at Fermilab, $143 \\pm 20$ $\\Sigma_c~0$ and $122 \\pm 18$ $\\Sigma_c~{++}$ through their de…

Results on charm production from E791, a high statistics charm hadroproduction experiment at Fermilab Open
Fermilab experiment E791 collected a large sample of charm events to study several aspects of charm physics. Many topics on production and decay of charm particles can be covered with this data set. This talk will concentrate on the produc…
