“…In order to tune the shower and light quark hadronization parameters we used data on jet rates and event shapes for centre-of-mass energies between 14 and 44 GeV [40][41][42][43], at LEP1 and SLD [42][43][44][45][46][47] and LEP2 [42,43,46,47], particle multiplicities [44,45] and spectra [44,45,[48][49][50][51][52][53][54][55][56][57][58][59][60] at LEP 1, identified particle spectra below the Υ(4S) from Babar [61], the charged particle multiplicity and distributions from [62][63][64][65][66][67] for centre-of-mass energies between 14 and 61 GeV, the charged particle multiplicity [68,69] and particle spectra [68,70,71] in light quark events at LEP1 and SLD, the charged particle multiplicity in light quark events at LEP2 [72,73], the cha...…”

We study the logarithmic accuracy of angular-ordered parton showers by considering the singular limits of multiple emission matrix elements. This allows us to consider different choices for the evolution variable and propose a new choice which has both the correct logarithmic behaviour and improved performance away from the singular regions. In particular the description of e + e − event shapes in the non-logarithmic region is significantly improved.

“…Fragmentation processes have been studied in leptonhadron and hadron-hadron scattering, as well as in e þ e − annihilation, which provides the cleanest environment since no hadrons are present in the initial state. Due to the large amount of experimental data collected at several e þ e − facilities, mainly LEP [1][2][3] and SLC [4][5][6] at high energies, and, recently, PEP-II [7] and KEKB [8] at the center-of-mass energy ffiffi ffi s p ∼ 10 GeV, the unpolarized functions are presently well known.…”

We present measurements of Collins asymmetries in the inclusive process e þ e − → ππX, where π stands for charged pions, at a center-of-mass energy of 10.6 GeV. We use a data sample of 468 fb −1 collected by the BABAR experiment at the PEP-II B factory at SLAC, and consider pairs of charged pions produced in opposite hemispheres of hadronic events. We observe clear asymmetries in the distributions of the azimuthal angles in two distinct reference frames. We study the dependence of the asymmetry on several kinematic variables, finding that it increases with increasing pion momentum and momentum transverse to the analysis axis, and with increasing angle between the thrust and beam axis.

“…These include data for hadron production in: single-inclusive annihilation (SIA) (recently measured by BELLE [3, 4] and BABAR [5]), semi-inclusive deep-inelastic scattering (SIDIS) (recently measured by HERMES [6] and COMPASS [7, 8]) and proton-(anti)proton ( pp ) collisions (measured, e.g., by CDF [9, 10] at the Tevatron, STAR [11] and PHENIX [12] at RHIC and CMS [13, 14] and ALICE [15] at the LHC). These measurements span a wide range in energy and momentum fraction and are sensitive to different partonic combinations.…”

Charged hadron fragmentation functions from collider data

et al. 2018

We present NNFF1.1h, a new determination of unidentified charged-hadron fragmentation functions (FFs) and their uncertainties. Experimental measurements of transverse-momentum distributions for charged-hadron production in proton-(anti)proton collisions at the Tevatron and at the LHC are used to constrain a set of FFs originally determined from electron–positron annihilation data. Our analysis is performed at next-to-leading order in perturbative quantum chromodynamics. We find that the hadron-collider data is consistent with the electron–positron data and that it significantly constrains the gluon FF. We verify the reliability of our results upon our choice of the kinematic cut in the hadron transverse momentum applied to the hadron-collider data and their consistency with NNFF1.0, our previous determination of the FFs of charged pions, kaons, and protons/antiprotons.
