Femtoscopic Correlation Measurement with Symmetric Lévy-Type Source at NA61/SHINE
نویسندگان
چکیده
Measuring quantum-statistical, femtoscopic (including final state interactions) momentum correlations with interactions in high-energy nucleus-nucleus collisions reveal the space-time structure of particle-emitting source created. In this paper, we report NA61/SHINE measurements identified pion pairs and describe said based on symmetric Lévy-type sources Ar+Sc at 150A GeV/c. We investigate transverse mass dependence parameters discuss their possible interpretations.

Lévy NMF for robust nonnegative source separation
We address the problem of decomposing nonnegative data into meaningful structured components, which is referred to as latent variable analysis or source separation, depending on the community. It is an active research topic in many areas, such as music and image signal processing, applied physics and text mining. In this paper, we introduce the Positive α-stable (PαS) distributions to model the...
متن کاملUseful Martingales for Stochastic Storage Processes with Lévy-Type Input
In this paper we generalize the martingale of Kella and Whitt to the setting of Lévy-type processes and show that under some quite minimal conditions the local martingales are actually L martingales which upon dividing by the time index converge to zero a.s. and in L. We apply these results to generalize known decomposition results for Lévy queues with secondary jump inputs and queues with serv...
متن کاملThe Smile of Certain Lévy-Type Models
We consider a class of assets whose risk-neutral pricing dynamics are described by an exponential Lévy-type process subject to default. The class of processes we consider features locally-dependent drift, diffusion and default-intensity as well as a locally-dependent Lévy measure. Using techniques from regular perturbation theory and Fourier analysis, we derive a series expansion for the price ...
متن کاملFokker-Planck equations for stochastic dynamical systems with symmetric Lévy motions
The Fokker-Planck equations for stochastic dynamical systems, with non-Gaussian α−stable symmetric Lévy motions, have a nonlocal or fractional Laplacian term. This nonlocality is the manifestation of the effect of non-Gaussian fluctuations. Taking advantage of the Toeplitz matrix structure of the time-space discretization, a fast and accurate numerical algorithm is proposed to simulate the nonl...
متن کاملSource Shape Determination with Directional Correlation Functions
From the recent results of the 4 INDRA campaign at GSI, it has been found that central collisions of heavy symmetric systems lead to the formation of a heavy, hot and expanding composite nucleus, which exhibits pronounced anisotropies in the fragment yields and kinetic energies, as it has been observed in the Au+Au and Xe+Sn systems studied in the energy range of 40 to 150 A.MeV [1]. Both break...
