Awareness of ‘Systolic Anterior Motion’ in Different Conditions

open access: yesClinical Medicine Insights: Cardiology, 2018
Perioperative echocardiography, especially transesophageal echocardiography, is of paramount importance in evaluating and managing refractory hypotension, a potential cause of which is systolic anterior motion (SAM) of anterior mitral leaflet ...

Insight into particle production mechanisms via angular correlations of identified particles in pp collisions at $$\sqrt{\mathrm{s}}=7$$ s = 7  TeV

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
Two-particle angular correlations were measured in pp collisions at $$\sqrt{s} = 7$$ s = 7  TeV for pions, kaons, protons, and lambdas, for all particle/anti-particle combinations in the pair. Data for mesons exhibit an expected peak dominated by effects

Effect of thresholds on the width of three-body resonances

open access: yesPhysics Letters B, 2017
It has been recently reported an intriguing theoretical result of a narrow three-body resonance with a large available phase space [1]. The resonance was reported in the NΛΛ−ΞNN system near the Ξd threshold, having a very small width in spite of the open

Constraining baryon annihilation in the hadronic phase of heavy-ion collisions via event-by-event fluctuations

open access: yesPhysics Letters B, 2022
We point out that the variance of net-baryon distribution normalized by the Skellam distribution baseline, κ2[B−B¯]/〈B+B¯〉, is sensitive to the possible modification of (anti)baryon yields due to BB¯ annihilation in the hadronic phase.

Baryon-Baryon Interactions [PDF]

open access: yesProgress of Theoretical Physics Supplement, 2010
Summary: We review the Nijmegen extended-soft-core (ESC) models for the baryon-baryon (\(BB\)) interactions of the \(SU(3)\) flavor-octet of baryons \((N, \Lambda , \Sigma \), and \(\Xi )\). The interactions are basically studied from the meson-exchange point of view, in the spirit of the Yukawa-approach to the nuclear force problem [\textit{H. Yukawa},

S(3) skyrmions and the rational map ansatz [PDF]

open access: yes, 2000
This paper discusses multi-skyrmions on the 3-sphere with variable radius L using the rational map ansatz. For baryon number B = 3,...,9 this ansatz produces the lowest energy solutions known so far.

Dependence of net-hyperon production at mid-rapidity on beam energy and its implication on baryon number carrier [PDF]

open access: yesEPJ Web of Conferences
The conventional picture of baryon number is that each valence quark inside a baryon carries 1/3 unit of baryon number. However, an alternative picture exists where the center of a Y-shaped topology of gluon fields, called the baryon junction, carries 1 ...

Hadron resonance gas with repulsive interactions and fluctuations of conserved charges

open access: yesPhysics Letters B, 2018
We discuss the role of repulsive baryon–baryon interactions in a hadron gas using relativistic virial expansion and repulsive mean field approaches. The fluctuations of the baryon number as well as strangeness-baryon correlations are calculated in the ...

Many-Quark Interactions: Large-N Scaling and Contribution to Baryon Masses

open access: yesUniverse, 2022
Starting from an effective Hamiltonian modeling, of a baryon made of N identical quarks in the large-N approach of QCD, we obtain analytical formulas, allowing to estimate the contributions of multiquark interactions to the baryon mass.
