Precise measurement of Br($K^+ \to \pi^+ \nu \bar{\nu}$) at CERN SPS
  An experimental proposal to measure Br($K^+ \to \pi^+ \nu \bar{\nu}$) has been submitted at the CERN SPSC. The goal is to collect ~80 $K^+\to \pi^+ \nu \bar{\nu}$ events with signal to background ratio of 10:1 in two years of data taking. This will allow determination of the CKM parameter $V_{td}$ with ~10% accuracy.
