The b quark fragmentation fractions at LHCb and meson decays with heavy quark spectators
Abstract We study the current estimates of $$B_c\rightarrow B_s \pi $$ B c → B s π to extract the fragmentation fraction $$f_c/f_s$$ f c / f s at the LHCb. A rather robust estimate of $$Br(B_c\rightarrow B_s \pi )$$ B r ( B c → B s π ) based on factorization and lattice results for the form factor g...
