The QCD Critical End Point in the Context of the Polyakov--Nambu--Jona-Lasinio Model
Pedro Costa, C. A. de Sousa, M. C. Ruivo +1
We investigate the phase diagram of the so-called Polyakov--Nambu--Jona-Lasinio model at finite temperature and nonzero chemical potential with three quark flavors. Chiral and deco…
Interplay between chiral and axial symmetries in a SU(2) Nambu--Jona-Lasinio Model with the Polyakov loop
M. C. Ruivo, M. Santos, Pedro Costa +1
We consider a two flavor Polyakov--Nambu--Jona-Lasinio (PNJL) model where the Lagrangian includes an interaction term that explicitly breaks the U anomaly. At finite tempera…
On a coupled PDE model for image restoration
V. B. Surya Prasath, Dmitry Vorotnikov
In this paper, we consider a new coupled PDE model for image restoration. Both the image and the edge variables are incorporated by coupling them into two different PDEs. It is sho…
THGEM-based detectors for sampling elements in DHCAL: laboratory and beam evaluation
L. Arazi, A. Breskin, R. Chechik +17
We report on the results of an extensive R&D program aimed at the evaluation of Thick-Gas Electron Multipliers (THGEM) as potential active elements for Digital Hadron Calorimetry (…
Note on the Minimum Weight States in the su(2)-Algebraic Many-Fermion Model --- Extension of the Role of the Auxiliary su(2)-Algebra ---
Y. Tsue, C. Providencia, J. da Providencia +1
The role of the auxiliary su(2)-algebra proposed by the present authors in the latest paper is extended. Its aim is to determine the minimum weight states completely. With the aid…
Some operators that preserve the locality of a pseudovariety of semigroups
Alfredo Costa, Ana Escada
It is shown that if V is a local monoidal pseudovariety of semigroups, then K(m)V, D(m)V and LI(m)V are local. Other operators of the form Z(m)(_) are considered. In the process, r…
