Decay of D*(2010) \u2192 D0 \u03c0<\/h1>\n

Plot the mass distribution of a charged \"D^*\" which decays to a combination of \"D^0\pi^-\" or \"D^0 \pi^+\":<\/p>\n

  <\/span>   <\/span>\"\[D^0 \longrightarrow K^+π^- \quad\text{or}\quad D^0 \longrightarrow K^-\pi^+\]\"<\/p>\n

You will find a peak in the \"D^*\" mass distribution at at 2.01 \"\mathrm{GeV}/c^2\"<\/p>\n

Use the block ‘Combine 2 particles’ and describe the process in two stages.<\/p>\n

Be sure to select only the particles with a correct invariant mass of \"D^0\" for further analysis.<\/p>\n
