Isospin breaking in the pion-nucleon coupling constant and the nucleon-nucleon scattering length
Âderna Fìzika ta Energetika, 2016 Charge independence breaking (CIB) in the pion-nucleon coupling constant and the nucleon-nucleon scattering length is considered on the basis of the Yukawa meson theory.

Signal of the pion string at high-energy collisions [PDF]
Phys.Rev.C71:014902,2005, 2004 We study the possible signals of a pion string associated with the QCD chiral phase transition in LHC Pb - Pb collision at energy $ \sqrt{s}=5.5$ TeV. In terms of the Kibble-Zurek mechanism we discuss the production and evolution of the pion string. The pion string is not topologically stable, it decays into neutral pions and sigma mesons which in turn

Archaeometry, EarlyView.Abstract The research focuses on jewellery finds uncovered in the region of today's Czech Republic dated to the Great Migration Period. The metals and garnet inlays detected were examined with μ‐EDXRF, whereas, for glass samples, LA‐ICP‐MS was used. The paper presented is supplemented with data concerning the technological processing of the jewellery ...

, 2006 The mean field (MF) approximation for the pion matter, being equivalent to the leading ChPT order, involves no dynamical loops and, if self-consistent, produces finite renormalizations only.

British Journal of Educational Technology, EarlyView.Cognitive load is a critical internal state associated with learners' learning process and significantly influences learning outcomes. With the worldwide popularity of video‐based learning (VBL), tracking real‐time cognitive load variations becomes more and more important for the timely provision of adaptive learning support during the learning process.

Perioperative posterior ischemic optic neuropathy (PION) after open aortic surgery
Annals of Vascular Surgery - Brief Reports and Innovations, 2022 Perioperative posterior ischemic optic neuropathy (PION) is a rare but potentially devastating condition. A correlation of PION with major surgical procedures has been established, particularly in cases of spine and cardiovascular surgery.

Effects of pion potential and nuclear symmetry energy on the $π^{-}/π^{+}$ ratio in heavy-ion collisions at beam energies around the pion production threshold [PDF]
Phys. Rev. C 91, 054616 (2015), 2014 Within the framework of the isospin-dependent Boltzmann-Uehling-Uhlenbeck(IBUU) transport model, we studied the effects of the pion potential and the symmetry energy on the pion production in the central $^{197}Au+^{197}Au$ collisions around the pion production threshold.

Effects of multi-pion correlations on the source distribution in ultra-relativustic heavy-ion collisions [PDF]
Phys.Rev.C57:877-881,1998, 1998 Multi-pion correlation effect on the source distribution is studied. It is shown that multi-pion Bose-Einstein correlation make the average radius of the pion source become smaller. The isospin effect on the pion multiplicity distribution and the source distribution is also discussed.

Pion Compton scattering and bremsstrahlung
, 2008 The pion-polarizability functions are structure functions of pion-Compton scattering. They can be assessed in high-energy pion-nucleus bremsstrahlung reactions, $\pi^- +A\to\pi^- +\gamma +A$.
