New Measurement of BR(D+ ->Rho0 Mu+ Nu) / BR(D+ ->K*0 Mu+ Nu) Branching Ratio

The FOCUS collaboration, J. M. Link

Using data collected by the FOCUS experiment at Fermilab, we present a new measurement of the charm semileptonic branching ratio BR(D+ -> rho0 mu+ nu)/BR(D+ -> K*0 mu+ nu). From a…

A Non-parametric Approach to the D+ to K*0bar mu+ nu Form Factors

FOCUS Collaboration

Using a large sample of D+ -> K- pi+ mu+ nu decays collected by the FOCUS photoproduction experiment at Fermilab, we present the first measurements of the helicity basis form facto…

Study of Lambda/c+ Cabibbo Favored Decays Containing a Lambda Baryon in the Final State

FOCUS Collaboration

Using data from the FOCUS experiment (FNAL-E831), we study the decay of baryons into final states containing a hyperon. The branching fractions of into ,…

The Fine Structure Lines of Hydrogen in HII Regions

Brian Dennison, B. E. Turner, Anthony H. Minter

The 2s_{1/2} state of hydrogen is metastable and overpopulated in HII regions. In addition, the 2p states may be pumped by ambient Lyman-alpha radiation. Fine structure transitions…

A Measurement of the Ds+ Lifetime

FOCUS Collaboration, J. M. Link

A high statistics measurement of the Ds+ lifetime from the Fermilab fixed-target FOCUS photoproduction experiment is presented. We describe the analysis of the two decay modes, Ds+…

Hadronic Mass Spectrum Analysis of D+ into K- pi+ mu+ nu Decay and Measurement of the K*(892)^0 Mass and Width

FOCUS Collaboration, J. M. Link

We present a Kpi mass spectrum analysis of the four-body semileptonic charm decay D+ into K- pi+ mu+ nu in the range of 0.65 GeV < mKpi < 1.5 GeV. We observe a non-resonant contrib…

Application of Genetic Programming to High Energy Physics Event Selection

The FOCUS Collaboration, J. M. Link

We review genetic programming principles, their application to FOCUS data samples, and use the method to study the doubly Cabibbo suppressed decay D+ -> K+ pi+ pi- relative to its…
