Angular velocity is usually represented by the symbol omega ( ω, sometimes Ω). The SI unit of angular velocity is expressed as radians/sec with the radian having a dimensionless value of unity, thus the SI units of angular velocity are listed as 1/sec. In general, angular velocity is measured in angle per unit time, e.g. radians per second. the time rate of change of its angular position relative to the origin. Padmanath, and Debsubhra Chakraborty, 16 March 2023, Physical Review Letters.Orbital angular velocity refers to how fast a point object revolves about a fixed origin, i.e. Reference: “Strongly Bound Dibaryon with Maximal Beauty Flavor from Lattice QCD” by Nilmani Mathur, M. Lattice QCD calculations can also play a crucial role in understanding the nuclei formation at the Big Bang, their reaction mechanisms, in aiding the search for the physics beyond the standard model as well as for investigating the matter under the extreme conditions of high temperature and density similar to those at the early stages of the Universe after the Big Bang. In fact, some of the largest scientific computational resources in the world are being utilized by lattice gauge theorists who are trying to solve the mystery of strong interactions of our Universe through their investigations inside the femto-world (within a scale of about one million-billionth of a meter). Not only does it require a sophisticated understanding of the quantum field-theoretic issues, but the availability of large-scale computational resources is also crucial. Formulation of quantum chromodynamics (QCD) on space-time lattices, based on an intricate amalgamation between a fundamental theory and high-performance computing, provides an opportunity for such study. Since the strong force is highly non-perturbative in the low energy domain, there is no first-principles analytical solution as yet for studying the structures and interactions of composite subatomic particles like protons, neutrons, and the nuclei they form. It also brings motivation to search for such heavier exotic subatomic particles in next-generation experiments. This finding elucidates the intriguing features of strong forces in baryon-baryon interactions and leads the path for further systematic study of quark mass dependence of baryon-baryon interactions which possibly can explain the emergence of bindings in nuclei. Its binding energy is predicted to be as large as 40 times stronger than that of the deuteron, and hence perhaps entitled it to be the most strongly bound beautiful dibaryon in our visible universe. Schematic picture of the predicted dibaryon, D6b, made of two Omega baryons. Nevertheless, these dibaryons are not commonly observed - the deuteron is currently the only known stable dibaryon.
Fascinatingly, the strong force, responsible for the formation and the majority of the mass of nuclei, facilitates the formation of a plethora of different dibaryons with diverse quark combinations. Their formation, which occurs through interactions between baryons, is fundamental in big-bang nucleosynthesis, nuclear reactions including those happening within stars, and bridges the gap between nuclear physics, cosmology, and astrophysics. This discovery, made possible through Quantum Chromodynamics on space-time lattices, could provide valuable insights into the nature of strong forces and quark mass interactions.ĭibaryons are subatomic particles composed of two baryons. This particle, termed D6b, is predicted to have a binding energy 40 times stronger than that of the only known stable dibaryon, deuteron. Scientists from the Tata Institute of Fundamental Research and The Institute of Mathematical Science have predicted the existence of a dibaryon particle, built entirely from bottom quarks. The concept was first proposed in the context of quantum chromodynamics (QCD), the theory describing strong interactions between quarks and gluons.
Dibaryons, fascinating entities in nuclear and particle physics, represent a state of matter where two baryons, each consisting of three quarks, are bound together.
