  42. UCY-HEP Contributions Reconstruction of Φ(1020)→K+K- • The Φ(1020) meson is reconstructed looking at its decay into two charged kaons: Φ→K+K- • K± are reconstructed in the CMS tracker • Event and track selection • “Minimum bias” events at s½=0.9 TeV • Standard track quality cuts • Formed pairs with opposite-curvature tracks identified as kaons • K compatibility requested only for tracks with p<1GeV • If at least one track fails the dE/dx cut, no peak is visible

  43. UCY-HEP Contributions Φ(1020)→K+K- mass fit • Mass and resolution is in very good agreement respectively with PDG and simulation • Differences in S/B depend from bad MC reproduction of data – under investigation by CMS • Result in a public CMS note (CMS PAS TRK-10-001), a paper is in preparation Monte Carlo Simulation

  44. UCY-HEP Contributions Bose-Einstein Correlation (BEC) • Probability for identical boson particles (signal) to have similar momenta is enhanced with respect to uncorrelated case (reference) due to Bose-Einstein statistics • Studied as a ratio R(Q) between the signal and a reference distribution • Q depends on the 4-momentum difference • between the two particles • Distorsions due to reference are treated using double ratios Rdata/RMC and looking at several reference samples (7 in our case) • We verified that BEC is only present for identical particles

  45. UCY-HEP Contributions BEC – Results • BEC is seen as an enhancement of the ratio at low Q-values • The ratio is fitted assuming an exponential form of the correlation • Gaussian form (more used in literature) is very disfavored by our data • Some regions are excluded from the fit due to bad modeling of resonances in MC • The fit gives information on the size and shape of the particle-emitting region and on the strength of the correlation • These are the first measurements of the BEC in proton-proton collisions at 0.9 TeV and the first absolute measurement of BEC at 2.36 TeV

  46. UCY-HEP Contributions BEC – Dependence on Charged Multiplicity • We found an interesting effect linking the parameters of BEC to the total charged multiplicity in the event • The radius r is found to increase significantly with Ntracks • This effect is present in 0.9 TeV and in 2.36 TeV data (not shown in figure) • This has already been measured by other experiments in the past, although it seems that there is no simple theoretical explantion for it • Results in a public CMS note (CMS PAS QCD-10-003) and a paper
