CHARMING BARYONS [PDF]

open access: yesInternational Journal of Modern Physics: Conference Series, 2014
We study odd-parity baryonic resonances with one heavy and three light flavors, dynamically generated by meson-baryon interactions. Special attention is paid to Heavy Quark Spin Symmetry (HQSS), hence pseudoscalar and vector mesons and baryons with Jπ = 1/2+ and 3/2+ are considered as constituent hadrons.

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

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 ...

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

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.

Meson baryon components in the states of the baryon decuplet [PDF]

open access: yesEPJ Web of Conferences, 2014
We extend the Weinberg compositeness condition to partial waves of L = 1 and resonant states to determine the weight of meson-baryon component in the [Formula: see text] baryon decuplet. We obtain an appreciable weight of πN in the Δ(1232) wave function, of the order of 60 % and we also show that, as we go to higher energies in the members of the ...

Baryon Production in the String Fragmentation Picture [PDF]

open access: yes, 1996
An improved version of the ``pop-corn'' model for baryon production in quark and gluon jets is presented. With a reduced number of parameters the model reproduces well both production rates for different baryon species and baryon momentum distributions ...

Baryon Junction Stopping at the SPS and RHIC via HIJING/B [PDF]

open access: yes, 1998
Baryon stopping at the SPS and RHIC energies is calculated by introducing a new baryon junction mechanism into HIJING. The exchange of a baryon junction, according to Regge phenomenology, leads to a cosh(y/2) rapidity dependence and an s^(-1/4) energy ...

BARYONS WITH HOLOGRAPHY [PDF]

open access: yesModern Physics Letters A, 2008
We perform the first study of baryons in holographic QCD with [Formula: see text] multi-D-brane system in type IIA superstring theory. The baryon is described as a chiral soliton solution in the four-dimensional meson effective action derived from holographic QCD.

Lattice QCD at finite baryon density using analytic continuation

open access: yesEPJ Web of Conferences, 2018
We simulate lattice QCD with two flavors of Wilson fermions at imaginary baryon chemical potential. Results for the baryon number density computed in the confining and deconfining phases at imaginary baryon chemical potential are used to determine the ...
