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

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.

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

Baryon Number Fluctuation and the Quark-Gluon Plasma [PDF]

open access: yes, 2001
We show that $\omega_B$ or $\omega_{\bar B}$, the squared baryon or antibaryon number fluctuation per baryon or antibaryon, is a possible signature for the quark-gluon plasma that is expected to be created in relativistic heavy ion collisions, as it is a

Soft-core baryon-baryon potentials for the complete baryon octet [PDF]

open access: yesPhysical Review C, 1999
SU(3) symmetry relations on the recently constructed hyperon-nucleon potentials are used to develop potential models for all possible baryon-baryon interaction channels. The main focus is on the interaction channels with total strangeness S=-2, -3, and -4, for which no experimental data exist yet. The potential models for these channels are based on SU(

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.

A Note on Baryon-Baryon Interaction [PDF]

open access: yesProgress of Theoretical Physics, 1961
The process of a ( XI /sup -/ n) collision giving rise to hyperon systems is studied, the possibility of a bound state in the final system being also envisaged. The implication arising from the various parity assignments for the hyperons is discussed and the decay distribution of the possible bound system is analyzed. (L.N.N.)

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 ...
