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

Baryon decays to purely baryonic final states [PDF]

open access: yesScientific Reports, 2019
AbstractThe LHCb collaboration has presented first experimental evidence that spin-carrying matter and antimatter differ. The study looked at four-body decays of the $${{\boldsymbol{\Lambda }}}_{{\boldsymbol{b}}}^{{\bf{0}}}$$ Λ

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.

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 ...

Baryonic content of the pion

open access: yesPhysics Letters B, 2021
The baryon form factor of charged pions arises since isospin symmetry is broken. We obtain estimates for this basic property in two phenomenological ways: from simple constituent quark models with unequal up and down quark masses, and from fitting to e+e−

HYBRID BARYONS [PDF]

open access: yesBaryons 2002, 2003
We review the status of hybrid baryons. The only known way to study hybrids rigorously is via excited adiabatic potentials. Hybrids can be modelled by both the bag and flux-tube models. The low-lying hybrid baryon is N 1/2^+ with a mass of 1.5-1.8 GeV. Hybrid baryons can be produced in the glue-rich processes of diffractive gamma N and pi N production,
