Abstract

$z$-Scaling of inclusive spectra as a manifestation of self-similarity and fractality of hadron interactions is illustrated. The scaling for negative particle production in $Au+Au$ collisions from BES-I program at RHIC is demonstrated. The scaling variable $z$ depends on the momentum fractions of the colliding objects carried by the interacting constituents, and on the momentum fractions of the fragmenting objects in the scattered and recoil directions carried by the inclusive particle and its counterpart, respectively. Structures of the colliding objects and fragmentation processes in final state are expressed by fractal dimensions. Medium produced in the collisions is described by a specific heat. The scaling function $\psi(z)$ reveals energy, angular, multiplicity, and flavor independence. It has a power behavior at high $z$ (high $p_T$). Based on the entropy principle and $z$-scaling, energy loss as a function of the collision energy, centrality and transverse momentum of inclusive particle is estimated. New conservation law including fractal dimensions is found. Quantization of fractal dimensions is discussed., Comment: 19 pages, 9 figures; Presented at the 40th International Conference on High Energy Physics, ICHEP2020

5. Three-component multiplicity distribution, oscillation of combinants and properties of clans in $pp$ collisions at the LHC

High Energy Physics - Phenomenology
Abstract

Multiplicity distributions of charged particles measured by the ATLAS Collaboration in proton-proton collisions at $\sqrt{s}=8$ and 13 TeV are analyzed in the framework of a weighted superposition of three negative binomial distribution functions. The examination of the experimental data confirms the existence of a narrow peak at low multiplicities found earlier at $\sqrt{s}=0.9$ and 7 TeV. The peak is described by the third separate component of the total distribution. The energy dependence of the multiplicity characteristics of the three-component scenario is studied. It is demonstrated that the third multiplicity component might be responsible for oscillations of combinants observed lately in the analysis of the multiplicity distributions measured in proton-proton collisions at the LHC. Some consequences of the three-component description of the data for the clan parameters are analyzed., Comment: 24 pages, 21 figures

Subjects
High Energy Physics - Phenomenology
Abstract

The concept of z-scaling previously developed for analysis of inclusive reactions in proton-proton collisions is applied for description of processes with polarized particles. Hypothesis of self-similarity of the proton spin structure is discussed. The possibility of extracting information on spin-dependent fractal dimensions of hadrons and fragmentation process from the cross sections and asymmetries is justified. The double longitudinal spin asymmetry A_{LL} of jet and pi0-meson production and the coefficient of polarization transfer D_{LL} measured in proton-proton collisions at sqrt s = 200 GeV at RHIC are analyzed in the framework of z-scaling. The spin-dependent fractal dimension of proton is estimated., Comment: 4 pages, LaTeX, 6 figures, Presented at the XVI Workshop on High Energy Spin Physics (DSPIN-15), 8-12 September, 2015, Dubna, Russia

Abstract

New experimental data on transverse momentum spectra of strange particles (KS0, K-, K*, phi,...) produced in pp collisions at sqrt s = 200 GeV obtained by the STAR and PHENIX collaborations at RHIC are analysed in the framework of z-scaling approach. Scaling properties of the data z-presentation are illustrated. Self-similarity of strange particle production is discussed. A microscopic scenario of constituent interactions developed within the z-scaling approach is used to study constituent energy loss, proton momentum fraction and recoil mass in dependence on the transverse momentum, strangeness, and mass of the inclusive particle. The obtained results can be useful for understanding strangeness origin, for searching for new physics with strange probes and can serve as a benchmark for complex analyses of self-similar features of strange production in heavy ion collisions., Comment: 4 pages, LaTeX, 4 figures

Subjects
High Energy Physics - Phenomenology
Abstract

A possible signal of new phenomena emerging in the global characteristics of multiparticle production in hadron interactions at TeV energies is studied. The multiplicity distributions of charged particles measured in proton-proton collisions at the Large Hadron Collider at CERN are analyzed in the phenomenological framework of the weighted superposition of three negative binomial distribution functions. The examination of the experimental data indicates the existence of a narrow peak at low multiplicities which can be described by a separate component in the total distribution. The multiplicity characteristics of the third component reveal approximate energy and pseudorapidity invariance, of which a physical explanation represents a challenging problem in high energy multiple particle production., Comment: 32 pages, 18 figures, accepted for publication in Journal of Physics G: Nuclear and Particle Physics

11. Multiplicity distributions in proton-(anti)proton and electron-positron collisions with parton recombination

Author

Zborovský, I.

Subjects
High Energy Physics - Phenomenology
Abstract

A new approach to phenomenological description of the charged particle multiplicity distributions in proton-(anti)proton and electron-positron collisions is presented. The observed features of the data are interpreted on the basis of stochastic-physical ideas of multiple production. Besides the processes of parton immigration and absorption, two and three patron incremental and decremental recombinations are considered. The complex behaviour of the multiplicity distributions at different energies is described by four parametric generalized hypergeometric distribution (GHD). Application of the proposed GHD to data measured by the CMS, ALICE, and ATLAS Collaborations suggests that soft multiparton recombination processes can manifest itself significantly in the structure of multiplicity distribution in pp interactions at very high energies., Comment: 20 pages, 14 figures, 6 tables

Abstract

Experimental data on inclusive cross sections of the hadrons produced in high energy proton-(anti)proton collisions are analyzed in the z-scaling approach. Saturation of the scaling function PSI(z) for z<0.1 (low transverse momenta) was found. The first results on charged hadron spectra in pp collisions obtained by the CMS Collaboration at the LHC have confirmed the saturation down to the value of z=0.05. The CMS data on neutral K-meson production at s^{1/2}=7 TeV extend the saturation region even to a lower value of z=0.002 in the new energy domain. A microscopic scenario of hadron production at a constituent level based on the z-scaling is discussed in the saturation regime., Comment: Contribution to XXth International Baldin Seminar on High Energy Physics Problems: Relativistic Nuclear Physics and Quantum Chromodynamics (ISHEPP 2010) 4-9 Oct 2010, Dubna, Russia

Abstract

First results on charged hadron transverse momentum spectra in pp collisions obtained by the CMS Collaboration at LHC were analyzed in z-scaling approach. The first LHC data confirm z-scaling. The saturation regime of the scaling function psi(z) observed in pp and antp-pp interactions at lower energy sqrt s = 19-1960 GeV is verified. The saturation of psi(z) for charged hadrons is found down to z=0.05 at the highest energy sqrt s = 2360 GeV reached till now at colliders. A microscopic scenario of hadron production is discussed in connection with search for new signatures of phase transitions in hadron matter. Constituent energy loss and its dependencies on the transverse momentum of charged hadrons and collision energy are estimated. The beam energy scan at LHC in the saturation region is suggested., Comment: LaTeX, 6 pages, 6 figures

14. New properties of z-scaling: flavor independence and saturation at low z

Subjects
High Energy Physics - Phenomenology
Abstract

Experimental data on inclusive cross sections of particles produced in high energy proton-(anti)proton collisions at ISR, RHIC, and Tevatron are analyzed in the framework of $z$-scaling. New features of the scaling function $\psi(z)$ are established. These are flavor independence of $\psi(z)$ including particles with heavy flavor content and saturation at low $z$. The flavor independence means that the shape of the scaling function $\psi(z)$ is the same for different hadron species. The saturation corresponds to flattening of $\psi(z)$ for $z<0.1$. Relations of model parameters used in data $z$-presentation with some thermodynamical quantities (entropy, specific heat, temperature) are discussed. It is shown that behavior of the particle spectra at low $z$ is controlled by a parameter $c$ interpreted as a specific heat of the created medium associated with production of the inclusive particle. The saturation regime of $\psi(z)$ observed at low $z$ is assumed to be preferable in searching for phase transitions of hadron matter and for study of non-perturbative QCD in high energy proton-(anti)proton collisions at U70, RHIC, Tevatron, and LHC., Comment: 20 pages, 17 figures

Abstract

The experimental data on inclusive cross sections of jet, direct photon and hadron production in pp/antipp and AA collisions at RHIC and Tevatron are analyzed in the framework of z-scaling. Results of analysis are compared with data obtained at ISR, SppS and Tevatron. The properties of z-presentation of experimental data are verified. Physical interpretation of the scaling function and variable z is discussed. The locality, self-similarity and fractality are argued to reflect the general structure of the colliding objects, interaction of their constituents and particle formation at small scales. The obtained results suggest that the z-scaling may be used as a tool for searching for new physics phenomena beyond Standard Model in hadron and nucleus collisions at high transverse momentum and high multiplicity at U70, RHIC, Tevatron and LHC., Comment: 22 pages, LaTeX, 32 figures, Presented at the XVIII International Baldin Seminar on High Energy Physics Problems "Relativistic Nuclear Physics and Quantum Chromodynamics", Dubna, Russia, September 25-30, 2006

16. Generalized z-scaling in proton-proton collisions at high energies

Author

Subjects
High Energy Physics - Phenomenology
Abstract

New generalization of z-scaling in inclusive particle production is proposed. The scaling variable z is fractal measure which depends on kinematical characteristics of the underlying sub-process expressed in terms of the momentum fractions x1 and x2 of the incoming protons. In the generalized approach, the x1 and x2 are functions of the momentum fractions ya and yb of the scattered and recoil constituents carried out by the inclusive particle and recoil object, respectively. The scaling function psi(z) for charged and identified hadrons produced in proton-proton collisions is constructed. The fractal dimensions and heat capacity of the produced medium entering definition of the z are established to obtain energy, angular and multiplicity independence of the psi(z). The scheme allows unique description of data on inclusive cross sections of charged particles, pions, kaons, antiprotons and lambdas at high energies. The obtained results are of interest to use z-scaling as a tool for searching for new physics phenomena of particle production in high transverse momentum and high multiplicity region at proton-proton colliders RHIC and LHC., Comment: 20 pages, LaTeX, 21 figures, Presented at the Workshop of European Research Group on Ultra-Relativistic Heavy Ion Physics, Dubna, Russia, March 9-14, 2006

Abstract

Generalization of z-scaling observed in the inclusive high-pT charged hadron and jet production is proposed. The scaling function psi(z) describing both charged hadrons and jets produced in proton-(anti)proton collisions for various multiplicity densities and collision energies is constructed. Anomalous fractal dimensions and parameters characterizing associated medium for both classes of events are established. The basic features of the scaling established in minimum bias events are shown to be preserved up to the highest multiplicity densities measured in experiments UA1, E735, CDF and STAR.

Abstract

The properties of particle production in pp collisions are basis for analysis of pA and AA interactions and verification of theory. We analyzed inclusive particle production using z-scaling established in proton-proton and proton-antiproton collisions at the U70, ISR, Tevatron and RHIC. This scaling reflects symmetry of hadron structure, interaction and particle formation. It is shown that new data on charged hadron and pi0-meson spectra obtained in pp collisions at the Relativistic Heavy Ion Collider confirm the z-scaling., Comment: 7 pages, LaTeX, 4 figures, presented at the XVII International Conference on Ultra Relativistic Nucleus-Nucleus Collisions "Quark Matter'2004", January 11-17, 2004, Oakland, USA

Abstract

Assuming fractality of hadronic constituents, we argue that asymmetry of space-time can be induced in the ultra-relativistic interactions of hadrons and nuclei. The asymmetry is expressed in terms of the anomalous fractal dimensions of the colliding objects. Besides state of motion, the relativistic principle is applied to the state of asymmetry as well. Such realization of relativity concerns scale dependence of physical laws emerging at small distances. We show that induced asymmetries of space-time are a priori not excluded by the Michelson's experiment even at large scales., Comment: 29 pages, 3 figures

Abstract

The formation length of particles produced in the relativistic collisions of hadrons and nuclei has relevance to fundamental principles of physics at small interaction distances. The relation is expressed by z scaling observed in the differential cross sections for the inclusive reactions at high energies. The scaling variable reflects the length of the elementary particle trajectory in terms of a fractal measure. Characterizing the fractal approach, we demonstrate the relativity principles in space with broken isotropy. We derive relativistic transformations accounting for asymmetry of space-time expressed by different anomalous fractal dimensions of the interacting objects., Comment: 35 pages, 1 figure, latex

45. Top-quark p -spectra at CMS and flavor independence of z-scaling.

Author

Tokarev, M. and Zborovský, I.

Abstract

We present new results of analysis of top-quark differential cross sections obtained by the CMS Collaboration in pp collisions in the framework of the z-scaling approach. The spectra are measured over a wide range of collision energy $$\sqrt s = 7,8,13TeV$$ and transverse momentum p = 30−500 GeV/ c of top-quark using leptonic and jet decay modes. Flavor independence of the scaling function ψ( z) is verified in the new kinematic range. The results of analysis of the top-quark spectra obtained at the LHC are compared with similar spectra measured in $$\overline p p$$ collisions at the Tevatron energy $$\sqrt s = 1.96TeV$$ . A tendency to saturation of ψ(z) for the process at low z and a power-law behavior of ψ( z) at high z is observed. The measurements of high- p is observed. The measurements of highspectra of the top-quark production at highest LHC energy is of interest for verification of self-similarity of particle production, understanding flavor origin and search for new physics symmetries with top-quark probe.

Abstract

We present first measurements of the pseudorapidity and azimuth $(\eta,\phi)$ bin-size dependence of event-wise mean transverse momentum $$ fluctuations for Au-Au collisions at $\sqrt{s_{NN}} = 200$ GeV. We invert that dependence to obtain $p_t$ autocorrelations on differences $(\eta_\Delta,\phi_\Delta)$ interpreted to represent velocity/temperature distributions on ($\eta,\phi$). The general form of the autocorrelations suggests that the basic correlation mechanism is parton fragmentation. The autocorrelations vary strongly with collision centrality, which suggests that fragmentation is strongly modified by a dissipative medium in the more central Au-Au collisions relative to peripheral or p-p collisions. \\, Comment: 7 pages, 3 figures

Abstract

Experimental data on transverse momentum spectra of strange particles produced in collisions at obtained by the STAR and PHENIX collaborations at RHIC are analyzed in the framework of -scaling approach. The concept of the -scaling is based on fundamental principles of self-similarity, locality, and fractality of hadron interactions at high energies. General properties of the data -presentation are studied. Self-similarity of fractal structure of protons and fragmentation processes with strange particles is discussed. A microscopic scenario of constituent interactions developed within the -scaling scheme is used to study the dependence of momentum fractions and recoil mass on the collision energy, transverse momentum and mass of produced inclusive particle, and to estimate the constituent energy loss. We consider that obtained results can be useful in study of strangeness origin, in searching for new physics with strange probes, and can serve for better understanding of fractality of hadron interactions at small scales.

Abstract

P. Chaloupka for the STAR collaboration; We present $\pi - \Xi$ correlation analysis in Au-Au collisions at $\sqrt{S_{NN}}=200Gev $ and $\sqrt{S_{NN}}=62.4GeV$, performed using the STAR detector at RHIC. A $\Xi^*$(1530) resonance signal is observed for the first time in Au-Au collisions. Experimental data are compared with theoretical predictions. The strength of the $\Xi^*$ peak is reproduced in the correlation function assuming that $\pi$ and $\Xi$ emerge from a system in collective expansion.

Abstract

We report the first inclusive photon measurements about mid-rapidity (|y| photon photon decay channel. The fractional contribution of the pi0 -> photon photon decay to the inclusive photon spectrum decreases by 20% +/- 5% between pt = 1.65 GeV/c and pt = 2.4 GeV/c in the most central events, indicating that relative to pi0 -> photon photon decay the contribution of other photon sources is substantially increasing., 13 pages, 14 figures, submitted to Phys. Rev. C
