“…As the signal has a tail towards larger m values, the asymmetric Crystal Ball function [73] is used for the signal description. The shape of the background is parameterised with the Granet function [74]. An unbinned extended log likelihood fit [75] is performed using the RooFit framework [76].…”

“…Distortions of the line shape of ρ 0 have also been observed at RHIC in p + p and peripheral Au+Au collisions [12]. Dynamical interactions with the surrounding matter [7,8,13], interference between various scattering channels [14], phase-space distortions [7,8,13,[15][16][17][18][19][20], and Bose-Einstein correlations [7,8,15,[18][19][20] are possible explanations for the apparent modification of resonance properties.…”

“…The right and wrong charge m distributions are fitted simultaneously by means of an unbinned extended likelihood fit using RooFit [54] and ROOT [55]. The Crystal Ball [56] and Granet [57] probability distribution functions are used for modelling the signal and background, respectively. The fit to the total sample of selected D * candidates is shown for the right and wrong charge combinations in Fig.…”
