The self assembly processes of aromatic amino acids, phenylalanine, tyrosine, and tryptophan have been simulated were observed to form fibril-like aggregates linked certain rare diseases instances biological membrane disruption. Pure systems their mixtures studied systematically at constant temperatures free energy landscapes produced describing the height number assembled monomers associated with lower structures. Consistent some previous work, acid display a tendency arrange four-fold...
We present a Kπ mass spectrum analysis of the four-body semileptonic charm decay D+→K−π+μ+ν in range 0.65GeV/c2<mKπ<1.5GeV/c2. observe non-resonant contribution 5.30±0.74−0.96+0.99% with respect to total decay. For K∗(892)0 resonance, we obtain 895.41±0.32−0.43+0.35MeV/c2, width 47.79±0.86−1.06+1.32MeV/c2, and Blatt–Weisskopf damping factor parameter 3.96±0.54−0.90+1.31GeV−1. also report 90% CL upper limits 4% 0.64% for branching ratios Γ(D+→K¯∗(1680)0μ+ν)Γ(D+→K−π+μ+ν)...
Using a high statistics sample of photo-produced charm particles from the FOCUS experiment at Fermilab, we report on measurement ratio semileptonic rates \Gamma(D+ > ANTI-K pi mu+ nu)/\Gamma(D+ ANTI-K0 nu)= 0.625 +/- 0.045 0.034. Allowing for K S-wave interference measured previously by FOCUS, extract vector to pseudoscalar ANTI-K*0 0.594 0.043 0.033 and K- pi+ pi+)= 1.019 0.076 0.065. Our results show lower \Gamma(D K* \ell nu})/\Gamma(D nu) than has been reported recently indicate current...
Using a high statistics sample of photo-produced charm particles from the FOCUS experiment at Fermilab, we report results search for eight rare and Standard-Model-forbidden decays: D+, Ds+ > h+/- muon-/+ muon+ (with h=pion or Kaon). Improvement over previous by factor 1.7--14 is realized. Our branching ratio upper limit D+ pion+ muon- 8.8E-6 90% C.L. below current MSSM R-Parity violating constraint.
Using data collected by the fixed target Fermilab experiment FOCUS, we present several first measurements for semileptonic decay D0→K¯0π−μ+ν. a model that includes K¯0π− s-wave component, measure form factor ratios to be rv=1.71±0.68±0.34 and r2=0.91±0.37±0.10 amplitude A=0.35±0.22±0.05GeV−1. Finally, vector branching ratio Γ(D0→K*(892)−μ+ν)Γ(D0→K¯0π−π+)=0.337±0.034±0.013.
Using data collected by the fixed target Fermilab experiment FOCUS, we measure branching ratios of Cabibbo favored decays $Ξ_c^+ \to Σ^+K^-π^+$, Σ^+ \bar{K}^{*}(892)^0$, and Λ^0K^-π^+π^+$ relative to Ξ^-π^+π^+$ be $0.91\pm0.11\pm0.04$, $0.78\pm0.16\pm0.06$, $0.28\pm0.06\pm0.06$, respectively. We report first observation suppressed decay Σ^+K^+K^-$ ratio Σ^+K^-π^+$ $0.16\pm0.06\pm0.01$. also set 90% confidence level upper limits for ϕ$ Ξ^*(1690)^0(Σ^+ K^-) K^+$ 0.12 0.05, find an indication...
Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement of branching ratio for Cabibbo-favored decay mode D0→K−K−K+π+. From sample 143±19 fully reconstructed D0→K−K−K+π+ events, measure Γ(D0→K−K−K+π+)/Γ(D0→K−π−π+π+)=0.00257±0.00034(stat.)±0.00024(syst.). A coherent amplitude analysis has been performed to determine resonant substructure this mode. This reveals dominant contribution φ and K∗0(892) states.
Tyrosine, tryptophan, and phenylalanine are important aromatic amino acids for human health. If they not properly metabolized, severe rare mental or metabolic diseases can emerge, many of which researched enough due to economic priorities. In our previous simulations, all three these discovered be self-organizing have complex aggregations at different temperatures. Two essential stable formations observed during simulations: tubular-like spherical-like structures. this study, we develop...
