Models of baryon structure predict a small quadrupole deformation the nucleon due to residual tensor forces between quarks or distortions from pion cloud. Sensitivity quark versus degrees freedom occurs through Q2 dependence magnetic (M1+), electric (E1+), and scalar (S1+) multipoles in gamma*p-->Delta(+)-->p pi(0) transition. We report new experimental values for ratios E(1+)/M(1+) S(1+)/M(1+) over range = 0.4-1.8 GeV2, extracted precision p(e,e(')p)pi(0) data using truncated multipole...
A systematic analysis of transverse momentum and rapidity distributions measured in high-energy proton - (pp) collisions for energies ranging from 53 GeV to 7 TeV using Tsallis thermodynamics is presented. The excellent description all spectra obtained earlier analyses confirmed extended. All can be described by a single temperature 68 +/- 5 MeV at beam particle types investigated (43 total). value the entropic index, q, shows wider spread but always close q approx 1.146. These values are...
This work presents an analysis of fractional derivatives and fractal derivatives, discussing their differences similarities. The derivative is closely connected to Haussdorff's concepts dimension geometry. paper distinguishes between the a function on domain function, where image space. Different continuous approximations for are discussed, it shown that q-calculus approximation function. A similar version can be obtained Caputo's also proportional derivative, corresponding leads Caputo-like...
The predictions from a nonextensive self-consistent theory recently proposed are investigated. Transverse momentum (${p}_{T}$) distribution for several hadrons obtained in $p+p$ collisions analyzed to verify if there is evidence limiting effective temperature and entropic index. In addition, the hadron-mass spectrum that confronted with available data. It turns out all ${p}_{T}$ distributions mass good agreement experiment constant results confirm statistics plays an important role...
A system presenting fractal structure in its thermodynamical functions is introduced, and it shown that Tsallis statistics the correct framework for describing aspects of such fractal. Its Haussdorf dimension Lipshitz-H\"older exponent are determined terms entropic index $q$. The connections with intermittency experimental data discussed. thermofractal related to microscopic interaction components through S-matrix.
In this work we analyse how scaling properties of Yang-Mills field theory manifest as self-similarity truncated n-point functions by scale evolution. The presence such structures, which actually behaves fractals, allow for recurrent non-perturbative calculation any vertex. Some general are indeed independent the perturbative order, what simplifies calculations. We show that sufficiently high orders a statistical approach can be used, non extensive statistics is obtained, and Tsallis index,...
In this work, we study the formal connections between non-linear Fokker-Planck Equation associated with non-additive entropy and Boltzmann correlation functional. The collisional term following q-algebra is adopted. derivation of Equation, two constraints are imposed on final result: i) that entropic index q a characteristic parameter systems value does not change time, ii) for q→1 smooth transition standard obtained.
New cross sections for the reaction e p-->e p eta are reported total center of mass energy W = 1.5--1.86 GeV and invariant momentum transfer Q2 0.25--1.5 (GeV/c)(2). This large kinematic range allows extraction important new information about response functions, photocouplings, N coupling strengths baryon resonances. Newly observed structure at approximately 1.65 is shown to come from interference between S P waves can be interpreted with known Improved values derived photon amplitude...
The nonextensive self-consistent theory describing the thermodynamics of hadronic systems at high temperatures is used to derive some thermodynamical quantities, as pressure, entropy, speed sound and trace-anomaly. calculations are free fitting parameters, results compared lattice QCD calculations, showing a good agreement between data up around 175 MeV. Above this temperature effects singularity in partition function divergent behaviour respect with calculation.
The self-consistency of a thermodynamical theory for hadronic systems based on the non-extensive statistics is investigated. We show that it possible to obtain self-consistent according asymptotic bootstrap principle if mass spectrum and energy density increase q-exponentially. A direct consequence existence limiting effective temperature system. this result in agreement with experiments.
The emerging field of the Science Cities has revealed universal power-law trends in urban scaling, transcending cultural and geographic variations. This study investigates interplay between fundamental allometry, fractal dimensions, city social dynamics. By linking these factors to hierarchical structures defined by Dunbar’s numbers, a causal relationship is established that illuminates drivers scaling. Notably, this research highlights pivotal role Big Five personality traits shaping nature...
The role played by non-extensive thermodynamics in physical systems has been under intense debate for the last decades. With many applications several areas, Tsallis statistics have discussed detail works and triggered an interesting discussion on most deep meaning of entropy its complex systems. Some possible mechanisms that could give rise to formulated over years, particular a fractal structure thermodynamic functions was recently proposed as origin In present work, we investigate...
This study investigates the interconnections between traditional Fokker-Planck Equation (FPE) and its fractal counterpart (FFPE), utilizing derivatives. By examining continuous approximation of derivatives in FPE, it derives Plastino-Plastino (PPE), which is commonly associated with Tsallis Statistics. work deduces connections entropic index geometric quantities related to dimension. Furthermore, analyzes implications these relationships on dynamics systems spaces. To assess effectiveness...

The only slightly modified, but enough produce stars higher maximum masses. onsets constituents more strongly affected internal temperature decreases increase $q$-value,...
In this work, we provide an overview of the recent investigations on non-extensive Tsallis statistics and its applications to high energy physics astrophysics, including at Large Hadron Collider (LHC), hadron physics, neutron stars. We review some power-law distributions arising in experiments focusing a thermodynamic description system formed, which could explain behavior. The possible connections with fractal structure hadrons is also discussed. main objective present work delineate...
We investigate the transition from nucleon-meson to quark-gluon description of strong interaction using photon energy dependence d(γ,p)n differential cross section for energies above 0.5 GeV and center-of-mass proton angles between 30° 150°. A possible signature this is onset cross-section s−11 scaling with total squared, s, at some transverse momentum PT. The results show that has been reached about 1.1 GeV/c. This may indicate regime momentum.Received 21 April...
Particle production yields measured in central Au-Au collision at RHIC are obtained with free Fermi and Bose gases also a replacement of these statistics by non-extensive statistics. For the latter calculation, set different parameters was used values Tsallis parameter q chosen between 1.01 1.25, 1.16 generating best agreement experimental data, an indication that may be one underlying features heavy ion-collisions.
