Cumulants, free cumulants and half-shuffles [PDF]
Free cumulants were introduced as the proper analogue of classical cumulants in the theory of free probability. There is a mix of similarities and differences, when one considers the two families of cumulants. Whereas the combinatorics of classical cumulants is well expressed in terms of set partitions, that of free cumulants is described and often ...

Impact of resonance decays on critical point signals in net-proton fluctuations
The non-monotonic beam energy dependence of the higher cumulants of net-proton fluctuations is a widely studied signature of the conjectured presence of a critical point in the QCD phase diagram.

Numerical Generation of Trajectories Statistically Consistent with Stochastic Differential Equations [PDF]
A weak second-order numerical method for generating trajectories based on stochastic differential equations (SDE) is developed. The proposed approach bypasses direct noise realization by updating the system’s state using independent Gaussian random ...

Proton cumulants and correlation functions in Au + Au collisions at sNN=7.7–200 GeV from UrQMD model
We studied the acceptance dependence of proton cumulants (up to fourth order) and correlation functions in 0–5% most central Au+Au collisions at sNN=7.7, 11.5, 19.6, 27, 39, 62.4 and 200 GeV from UrQMD model.

Analogs of the Prime Number Problem in a Shot Noise Suppression of the Soft-Reset Process [PDF]
The soft-reset process, or a sequence of charge emissions from a floating storage node through a transistor biased in a subthreshold bias condition, is modeled by a master (Kolmogorov–Bateman) equation.

Collectivity in pp from resummed interference effects?
Azimuthal asymmetries vn in the soft transverse momentum spectra of hadronic collisions can result as a consequence of quantum interference and color flow which translates spatial anisotropies into momentum anisotropies via multipole radiation patterns ...

Net-particle number fluctuations in a hydrodynamic description of heavy-ion collisions [PDF]
Utilizing viscous hydrodynamic simulations of heavy-ion collisions, we study the behavior of cumulants of (net-)(anti)proton number distributions at RHIC beam energy scan energies, incorporating non-critical contributions like baryon conservation and ...

A Fourier-cumulant analysis for multiharmonic flow fluctuation
The Fourier analysis of the final particle distribution followed by cumulant study of the Fourier coefficient event-by-event fluctuation is one of the main approaches for testing the collective evolution in the heavy-ion collision.

Effects of Initial Density Fluctuations on Cumulants in Au + Au Collisions at
Within the ultrarelativistic quantum molecular dynamics (UrQMD) model, the effect of initial density fluctuations on cumulants of the net-proton multiplicity distribution in Au + Au Collisions at sNN = 7.7 GeV was investigated by varying the minimum ...
