---+ V0 Femtoscopy in pPb @ 8.16 !TeV

Analysis of V0's at CMS in !pPb@8.16TeV. The main idea is to do this analysis using K0s and Lambdas and study the strong iterations.

   * V0 Reconstruction Cuts:
      * aa
   * Femtoscopy Cuts:
      * High Purity
      * |&eta;| &lt; 2.4
      * pT &gt; 0.2 !GeV
      * NV0 &gt;= 2
      * Nmix = 5
      * Daughters with at least 1 pixel hit (remove some contamination)
      * Mass Signal and Sideband are extracted by mass fits (using mean and sigma - see section X)
         * Mean - 2*sigma &lt; Mass Signal &lt; Mean + 2*sigma
         * Mean - 5*sigma &lt; Mass Sideband or Mass Sideband &gt; Mean + 5*sigma
   * Padova Selection (remove splitting tracks and duplicated) -&gt; we decide to use that in our analysis
      * cos &theta;ij &lt; 0.99996
      * &Delta;pT &lt; 0.04 !GeV
      * Padova cuts require qinv &gt; 0.04 !GeV (i will include some plots to show that)
   * Daughter Matching (&Delta;X = xi - xj, where xi and xj are the daughter with the same charge comming from different V0)<br />
      * &Delta;pT &lt; 0.04 !GeV
      * &Delta;&phi; &lt; 0.04
      * &Delta;&eta; &lt; 0.04
      * Compatible with Padova cuts (i will include some plots to show that)
