Dedication to Nathan Isgur [PDF]

open access: yes, 2002
Nathan passed away in July after a lengthy illness. I am sure most of you are familiar with his many contributions to heavy quark physics and it is certainly fitting that we take a few minutes to honor him at the beginning of this meeting.

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

Understanding pentaquarks with various quark models [PDF]

open access: yesPhysics Letters B, 2004
The pentaquark state recently discovered has been studied with three quark models which either fit the nucleon spin structure or the $NN$ scattering. A minimum $ ^+$ mass of 1620 MeV is obtained both for the ${1/2}^\pm$ state. The mixing of various color structure configurations, which would reduce the mass of the penta-quark state, should be taking ...

Rationality and hinge disagreements: A critique of constitutivism

open access: yesMetaphilosophy, EarlyView.
Abstract Can we rationally choose between philosophical hinge commitments if they resist argument and evidence? At first glance, such choices seem arbitrary. Coliva and Palmira (2020, 2021) and Coliva and Doulas (2022) argue, however, that adopting a constitutivist account of hinges allows for rational choice through what Coliva terms ‘extended ...

Pion parton distribution functions with the nonrelativistic constituent quark model

open access: yesNuclear Physics B, 2023
We calculate the valence quark distribution functions of the π meson using the non-relativistic chiral constituent quark model. The π wave function is obtained by solving the two-body Schrödinger equation within the framework of constituent quark model ...

Process and individuation (on speculative realism and becoming)

open access: yesThe Southern Journal of Philosophy, EarlyView.
Abstract Recent developments in the continental tradition have taken a realist turn that reveals an oscillation between, on the one hand, an ontology of virtuality that thinks of reality as process and continuum (albeit a continuum of differences or events) and, on the other hand, the resurgence of an ontology of objects and essences guided by the ...

Search for single production of vector-like quarks decaying into Wb in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
A search for singly produced vector-like quarks Q, where Q can be either a T quark with charge +2/3 or a Y quark with charge −4/3, is performed in proton–proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity

Color superconductivity in the static Einstein Universe [PDF]

open access: yes, 2007
We study the behavior of quark and diquark condensates in dense quark matter under the influence of a gravitational field adopting as a simple model the static $D-$dimensional Einstein Universe. Calculations are performed in the framework of the extended
