Quark: Controllable Text Generation with Reinforced Unlearning [PDF]

open access: yesNeural Information Processing Systems, 2022
Large-scale language models often learn behaviors that are misaligned with user expectations. Generated text may contain offensive or toxic language, contain significant repetition, or be of a different sentiment than desired by the user. We consider the

Test of lepton universality in beauty-quark decays [PDF]

open access: yesNature Physics, 2021
The standard model of particle physics currently provides our best description of fundamental particles and their interactions. The theory predicts that the different charged leptons, the electron, muon and tau, have identical electroweak interaction ...

Polarization and Vorticity in the Quark–Gluon Plasma [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2020
The quark–gluon plasma (QGP) produced by collisions between ultrarelativistic heavy nuclei is well described in the language of hydrodynamics. Noncentral collisions are characterized by very large angular momentum, which in a fluid system manifests as ...

Tetra- and Penta-Quark Structures in the Constituent Quark Model [PDF]

open access: yesSymmetry, 2020
With the development of high energy physics experiments, a large amount of exotic states in the hadronic sector have been observed. In order to shed some light on the nature of the tetraquark and pentaquark candidates, a constituent quark model, along ...

J-PARC Hadron Physics and Future Possibilities on Color Transparency

open access: yesPhysics, 2022
The Japan Proton Accelerator Research Complex (J-PARC) is a hadron-accelerator facility that aims to provide secondary beams of kaons, pions, neutrinos, muons, and others together with the primary proton beam for investigating a wide range of science ...

Quaternion Algebra on 4D Superfluid Quantum Space-Time: Can Dark Matter Be a Manifestation of the Superfluid Ether?

open access: yesUniverse, 2021
Quaternions are a natural framework of 4D space-time, where the unit element relates to time, and three others relate to 3D space. We define a quaternion set of differential torsion operators (shifts with rotations) that act to the energy-momentum tensor

Bulk strong matter: the trinity

open access: yesAdvances in Physics: X, 2023
Our world is wonderful because of the normal but negligibly small baryonic part (i.e. atoms) although unknown dark matter and dark energy dominate the Universe.

Nutritive characteristics of probiotic quark as influenced by type of starter [PDF]

open access: yesActa Periodica Technologica, 2007
Quark was manufactured, under laboratory conditions, by standard batch process, from two types of milk: I) partially skimmed, with 1.6 % of fat and II) whole milk, with 3.5 % of fat.

Evidence for quark-matter cores in massive neutron stars [PDF]

open access: yesNature Physics, 2019
The theory governing the strong nuclear force—quantum chromodynamics—predicts that at sufficiently high energy densities, hadronic nuclear matter undergoes a deconfinement transition to a new phase of quarks and gluons1.

Effects of Gravitational Field of a Topological Defect on Statistical Properties of Heavy Quark-Antiquark Systems

open access: yesEast European Journal of Physics, 2022
In this paper, we determine eigen energies, eigenfunctions and statistical properties of non-relativistic heavy quarkonia interacting with the extended Cornel potential within a space-time generated by a cosmic-string.
