Title: New measurement of BR(D+ ---> rho0 mu+ nu) / BR(D+ ---> anti-K*0 mu+ nu) branching ratio

Abstract

Using data collected by the FOCUS experiment at Fermilab, the authors present a new measurement of the charm semileptonic branching ratio BR(D{sup +} {yields} {rho}{sup 0}{mu}{sup +}{nu})/BR(D{sup +}{yields}{bar K}*{sup 0} {mu}{sup +}{nu}). From a sample of 320 {+-} 44 and 11,372 {+-} 161 D{sup +} {yields} {rho}{sup 0}{mu}{sup +}{nu} and D{sup +} {yields} K{sup -}{pi}{sup +}{mu}{sup +}{nu} events respectively, they find BR(D{sup +} {yields} {rho}{sup 0}{mu}{sup +}{nu})/BR(D{sup +}{yields}{bar K}*{sup 0} {mu}{sup +}{nu}) = 0.041 {+-} 0.006(stat) {+-} 0.004(syst).
