Analysis of Bose-Einstein correlation at 7 TeV by LHCb collaboration based on stochastic approach

The Bose–Einstein correlation (BEC) in forward region (2.0 < η < 4.8) measured at 7 TeV in the Large Hadron Collider (LHC) by the LHCb collaboration is analyzed using two conventional formulas of different types named CFI and CFII. The first formula is well known and contains the degree of coh...

description The Bose–Einstein correlation (BEC) in forward region (2.0 < η < 4.8) measured at 7 TeV in the Large Hadron Collider (LHC) by the LHCb collaboration is analyzed using two conventional formulas of different types named CFI and CFII. The first formula is well known and contains the degree of coherence (λ) and the exchange function EBE2 from the BE statistics. The second formula is an extended formula (CFII) that contains the second degree of coherence λ2 and the second exchange function EBE 22 in addition to CFI. To examine the physical meaning of the parameters estimated by CFII, we analyze the LHCb BEC data by using a stochastic approach of the three-negative binomial distribution and the three-generalized Glauber–Lachs formula. Our results reveal that the BEC at 7 TeV consisted of three activity intervals defined by the multiplicity n ([8, 18], [19, 35], and [36, 96]) can be well explained by CFII.

The first formula is well known and contains the degree of coherence ($\lambda$) and the exchange function $E_{\rm BE}^2$ from the BE statistics. The second formula is an extended formula (CF$_{\rm II}$) that contains the second degree of coherence $\lambda_2$ and the second exchange function $E_{\rm BE_2}^2$ in addition to CF$_{\rm I}$. To examine the physical meaning of the parameters estimated by CF$_{\rm II}$, we analyze the LHCb BEC data by using a stochastic approach of the three-negative binomial distribution and the three-generalized Glauber-Lachs formula. Our results reveal that the BEC at 7 TeV consisted of three activity intervals defined by the multiplicity $n$ ([8, 18], [19, 35], and [36, 96]) can be well explained by CF$_{\rm II}$.arXiv:2003.00427oai:cds.cern.ch:27592532020-03-01
