We study scalar, pseudoscalar, vector, and axial-vector mesons with non-strange strange quantum numbers in the framework of a linear sigma model global chiral $U(N_f)_L \times U(N_f)_R$ symmetry. perform fit meson masses, decay widths, as well amplitudes. The quality is, for hadronic that does not consider isospin-breaking effects, surprisingly good. also investigate question whether scalar $\bar{q}q$ states lie below or above 1 GeV find to be preferred states. Additionally, we describe resonances
The chiral phase transition of the strongly interacting matter is investigated at nonzero temperature and baryon chemical potential mu_B within an extended (2+1) flavor Polyakov constituent quark-meson model which incorporates effect vector axial mesons. fermionic vacuum thermal fluctuations computed from grand taken into account in curvature masses scalar pseudoscalar parameters are determined by comparing tree-level decay widths with experimental values a chi^2-minimization procedure...
The existence of quark matter inside the heaviest neutron stars has been topic numerous recent studies, many them suggesting that a phase transition to strongly interacting conformal is feasible. Here we examine this hybrid star scenario using soft and stiff hadronic model, constituent model with three flavours, applying smooth crossover between two. Within Bayesian framework, study effect up-to-date constraints from observations on equation-of-state parameters various observables. Our...
When the quark masses are lighter than those in QCD, standard lore is that a chiral transition of first order must emerge for three light flavors. Recently, however, numerical simulations on lattice suggest second limit. Using an extended linear sigma model mean field approximation, we study relation between terms which break anomalous, <a:math xmlns:a="http://www.w3.org/1998/Math/MathML" display="inline"><a:mi>U</a:mi><a:mo stretchy="false">(</a:mo><a:mn>1</a:mn><a:msub><a:mo...

Mixed-polytype ZnS single crystals doped with various $3{d}^{5}$ ions (${\mathrm{Cr}}^{+}$, ${\mathrm{Mn}}^{++}$, and ${\mathrm{Fe}}^{3+}$) have been examined by electron-paramagnetic-resonance techniques. It was found that three kinds of sites exist in these crystals, one cubic two axial symmetry around the $c$ axis "hexagonal" crystals. None centers correspond to characteristic a true wurtzite crystal. A model crystallographic nature based on point-charge calculation is proposed which...
The Cosmic Ray Extremely Distributed Observatory (CREDO) is a newly formed, global collaboration dedicated to observing and studying cosmic rays (CR) ray ensembles (CRE): groups of minimum two CR with common primary interaction vertex or the same parent particle. CREDO program embraces testing known CRE scenarios, preparing observe unexpected physics, it also suitable for multi-messenger multi-mission applications. Perfectly matched capabilities, could be formed both within classical models...
During vapour phase soldering, size of the sample tray determines number soldered assemblies. The aim our research was to investigate if productivity an industrial-grade oven could be improved for more energy-efficient production without making significant retrofitting modifications, and validate results by investigating soldering quality. tripled stacking Furthermore, a with reduced thermal mass applied, shortening cycle time 20%. Comparative tests were performed between vertical...
The boundary of the first order chiral phase transition region is studied in ${m}_{\ensuremath{\pi}}\ensuremath{-}{m}_{K}\ensuremath{-}{\ensuremath{\mu}}_{B}$ space using one-loop optimized perturbation theory for resummation perturbative series. Chiral mesons and baryons used $T=0$ parametrization model. surface second points bends with increasing ${\ensuremath{\mu}}_{B}$ towards physical point ${m}_{\ensuremath{\pi}}\ensuremath{-}{m}_{K}$ mass plane allowing existence critical end...

We comment on the paper of S. Postnikov et al. [Phys. Rev. D 82, 024016 (2010)] and give a modified formula that needs to be taken into account when calculating tidal Love number neutron stars in case first order phase-transition occurs at nonzero pressure. show error made using original tends zero as $p\ensuremath{\rightarrow}0$, we estimate maximum relative $\ensuremath{\sim}5%$ if density discontinuity is larger densities.

The effect various chemical potentials introduced in grand canonical ensemble is investigated with method relativistic many-body theory. temperature...
The existence of quark matter inside the cores heavy neutron stars is a possibility which can be probed with modern astrophysical observations. We use vector and axial-vector meson extended quark-meson model to describe in core stars. discover that an additional parameter constraint necessary ensure chiral restoration at high densities. By investigating hybrid star sequences various sets, we show low sigma masses are needed fulfill upper radius constraints maximum mass stable only slightly...

The authors study the phase diagram of QCD-like theories, in plane temperature and chemical potential, using a Polyakov loop model. As number colors increases, crossover line for chiral transition enlarges, splits from that deconfinement, then turns into first order deconfinement.
The electrochemical corrosion of quenched metallic glasses was investigated by the potentiostatic polarization method. Room temperature Mòssbauer spectra were also measured to obtain information about state samples. measurements used current‐voltage curves over a range −800 +200 mV (vs. SHE) in order study effects boron content, melt overheating, quenching rate, relaxation, and crystallization processes on current. It found that current varied with rate influenced content investigated....
We study the well-known resonance $$\psi (4040)$$ , corresponding to a $$3^{3}S_{1}$$ charm–anticharm vector state (3S)$$ within QFT approach, in which decay channels into DD, $$D^{*}D$$ $$D^{*}D^{*}$$ $$D_{s}D_{s}$$ and $$D_{s}^{*}D_{s}$$ are considered. The spectral function shows sizable deviations from Breit–Wigner shape (an enhancement, mostly generated by $$DD^{*}$$ loops, occurs); moreover, besides $$c{\bar{c}}$$ pole of second dynamically broad at 4 GeV emerges. Naively, it is...
