Direct measurement of the pion valence quark momentum distribution, the pion light-cone wave function squared

E791 Collaboration, E. M. Aitala

We present the first direct measurements of the pion valence quark momentum distribution which is related to the square of the pion light-cone wave function. The measurements were…

Experimental evidence for a light and broad scalar resonance in $D^{+} \to π^{-} π^{+} π^{+}$ decay

E791 Collaboration

From a sample of $1172 \pm 61$ $D^{+} \to π^{-} π^{+} π^{+}$ decay, we find $Γ (D^{+} \to π^{-} π^{+} π^{+}) /Γ (D^{+} \to K^{-} π^{+} π^{+}) = 0.0311 \pm 0.001 8_{- 0.0026}^{+ 0.0016}$ . Using a coherent amp…

Measurement of the form-factor ratios for D^+ -> \overline K^{*0}e^+ν_e

Fermilab E791 Collaboration, E. M. Aitala

We present a measurement of the form-factor ratios r_V=V(0)/A_1(0) and r_2=A_2(0)/A_1(0) for the decay D^+ -> \overline K^{*0} e^+ ν_e. The measurement is based on a signal of appr…
