Cuts used for all my peaks:

V0 reconstruction (both K0, Lambda and g->e+e-):

1. Track selection:

- 2 tracks of opposite charge with measurements in CFT.
- dp/p < 0.5 (dp - precision of momentum measurement).
- (impact(axial)/sigma)^2 + (impact(stereo)/sigma)^2 > 16.
  here impact is the impact of the track to the primary vertex

NO CUT ON TRACK MOMENTUM.

2. V0 selection

- Two tracks make a vertex with Chi2 < 25.
- Number of missed hits between vertex and the first measured point on
  track does not exceed 1 (for each track).
- Sum of hits on 2 tracks downstream to the found vertex is less than 3.
- l/sigma(l) > 4, where l is the distance between primary and decay
  vertices
- (impact(axial)/sigma)^2 + (impact(stereo)/sigma)^2 < 36,
  here impact is the impact of Ks track to the primary vertex.

- for K0s, the mass window: 0.475 - 0.5225
- for Lambda, the mass window: 1.108-1.125
- for gamma*, Mee < 0.025 GeV

-----------------------------------------------

For J/psi K+ selection:

1. Track selection of J/psi candidate:

- 2 tracks of opposite sign with pt>1.5 GeV;
- at least 1 CFT measurement;
- dp/p < 0.5 (dp - precision of momentum measurement);
- Number of backward misses (misses between the first measured point
  and the primary vertex) is less than 2;
- impact (axial and stereo) is less than 3 mm or
  (impact(axial)/sigma)^2 + (impact(stereo)/sigma)^2 < 25.;
- at least 1 track should have measurements in SMT;
- reject track if it was identified as the decay product of K0, Lambda,
  gamma->e+e-;

2. Jet clustering:

- Durham algorithm using pyclus subroutine from PYTHIA
- clustering parameter (PARU(45)) = 15 GeV;

3. J/psi selection:

- total momentum of J/psi > 5.0 GeV;
- pt of J/psi             > 4.0 GeV;
- both tracks are from the same jet, or their Pt exceeds 2.5 GeV;

NO MUON IDENTIFICATION for the moment. It's just a technical problem,
since I don't have in my special DST muon information yet. In principle,
muon identification can be very useful.

With these selections I have about 35000 J/psi events in the reprocessed
sample (sets 1,3,4,5, 1/2 of set2).

4. K+ candidate selection:

 - reject track if it was identified as the product of K0, Lambda,
   gamma->e+e-;
 - pt > 0.5 GeV;
 - at least 1 measurement in CFT;
 - K+ should be from the same jet as J/psi;
 - impact(axial)/sigma > 2. or
   (impact(axial)/sigma)^2 + (impact(stereo)/sigma)^2 > 9.;
 - Number of backward misses (see above for definition) < 2;
 - Number of forward misses (missed hits between the last measured
   point and the end of detector) < 3;

5. B+->J/psi K+ candidate selection:

 - at least 2 particles have measurements in SMT;
 - Three particles make the vertex, such that addition of each particle
   does not increase Chi2 of vertex more than 36.;
 - l/sigma(l) > 3, where l is the distance between primary and secondary
   vertex;
 - if momentum of K+ candidate < 1.0 Gev: l/sigma(l) > 4;
 - (impact(axial)/sigma)^2 + (impact(stereo)/sigma)^2 < 64,
   here impact is the impact of B+ track to the primary vertex;
 - cos(alpha) > 0.9, where alpha is the angle between B+ momentum
   and the direction from primary to secondary vertex;

That's all.

For J/psi K*

1,2,3 - exactly as above

For K* selection:

 - 2 tracks of opposite charge
 - reject track if it was identified as the product of K0, Lambda,
   gamma->e+e-;
 - pt > 0.5 GeV of each track;
 - at least 1 measurement in CFT;
 - K+ and pi should be from the same jet as J/psi;
 - Number of backward misses (see above for definition) < 2;
 - Number of forward misses (missed hits between the last measured
   point and the end of detector) < 3;

5. B+->J/psi K*+ candidate selection:

 - at least 2 particles have measurements in SMT;
 - Four particles make the vertex, such that addition of each particle
   does not increase Chi2 of vertex more than 36.;
 - l/sigma(l) > 3, where l is the distance between primary and secondary
   vertex;
 - if momentum of K+ or pi- < 1.0 Gev: l/sigma(l) > 4;
 - (impact(axial)/sigma)^2 + (impact(stereo)/sigma)^2 < 64,
   here impact is the impact of Bd track to the primary vertex;
 - cos(alpha) > 0.9, where alpha is the angle between B+ momentum
   and the direction from primary to secondary vertex;
 - select (K+ pi-) pair with the mass within 0.820-0.940 window;
   if both combinations are in this window, select the combination
   with the mass closest to the nominal K*;

That's all;

---------------------------------------------------------

For Bd->J/psi K0s:

1,2,3 as above, K0s as above.

 Bd->J/psi K0s selection:

 - Both particles of J/psi should have the measurements in SMT;
 - 2 mouns and K0s make the vertex, such that chi2(vrt) < 25.;
 - l/sigma(l) > 3, where l is the distance between primary and secondary
   vertex;
 - (impact(axial)/sigma)^2 + (impact(stereo)/sigma)^2 < 36;
   here impact is the impact of Bd track to the primary vertex;
 - cos(alpha) > 0.9, where alpha is the angle between B+ momentum
   and the direction from primary to secondary vertex;
 - Pt of K0s > 0.5 GeV;
 - mass constraints both for J/psi and K0s

That's all;
