|−|On the uPDFs in the usual gluon PDFs working with varying prescriptions. The latest analyses [1221,1222] show incredibly great agreement with J/ photoproduction information at HERA [1169?171,1185] and hadroproduction at the LHC [1142,1144,1182]. On leading of that, the J/ is predicted to be largely unpolarized, in line with all recent polarization measurements; see paragraph d in Sect. four.five.1. As for hadroproduction, the conclusions are however contrary to the author's earlier findings , which show longitudinal J/ polarization and cross sections an order of magnitude beneath the CDF production information. In addition they disagree using the recent operate , where J/ hadroproduction at the LHC was studied within the exact same way, comparing for the similar information [1142,1144,1182], even when the exact same uPDFs [1225,1226]2981 Web page 80 of 241 Table 14 Colour singlet model predictions for (e+ e- J/ + c ) when compared with B-factory information [1204?206]. As for the theoretical predictions for the leading-order cross section also because the corrections of order O(s ), O(v two ), and O(s v 2 ), we examine the outcomes obtained [https:// dx.doi.org/ 10.1098/rstb.2015.0074 title= rstb.2015.0074] in [1207?209]. These calculations [https://www.medchemexpress.com/CY5- SE.html Cy5 NHS Ester site] mostly differ by various procedures of color singlet LDME determinations.

Right here, the colour singlet predictions lie once again clearly beneath the data, plus the difference was even utilized to fit the CO LDMEs of NRQCD in a kT factorization method.
