The longstanding discrepancy between the theoretical and experimental values of the muon's magnetic moment (g-2) has been resolved, confirming the Standard Model's predictions and showcasing the importance of precise experiments and advanced computational methods like lattice QCD in understanding fundamental physics.
A new study using lattice QCD techniques has calculated the equation of state of the quark-gluon plasma from 3 GeV to 165 GeV, revealing that the strong force played a significant role in the early universe's conditions shortly after the Big Bang, with implications for understanding the universe's evolution and phase transitions.
A new study combining experimental data and lattice Quantum Chromodynamics (QCD) calculations has provided deeper insights into the contributions of gluons to the proton's spin. This collaborative effort, led by Joseph Karpie at Jefferson Lab, aims to resolve the decades-old mystery of proton spin and paves the way for a three-dimensional understanding of the proton's structure.
Physicists from the Tata Institute of Fundamental Research and The Institute of Mathematical Science have predicted the existence of a new subatomic particle, a deeply bound dibaryon made entirely from bottom quarks. The dibaryon, named D6b, is composed of two triply bottom Omega baryons and is predicted to be 40 times stronger than the deuteron, making it the most strongly bound beautiful dibaryon in the visible universe. The finding provides insight into the strong forces in baryon-baryon interactions and motivates the search for heavier exotic subatomic particles in next-generation experiments.
Scientists have determined the gluonic gravitational form factors of the proton, which describe the distribution of the proton's mass and energy. The research was conducted using data from an electron-proton scattering experiment and analyzed using quantum chromodynamics and lattice QCD. The results provide insight into the structure of the proton and could aid in the development of an electron-ion collider, a proposed particle accelerator that could further advance our understanding of the fundamental building blocks of matter.
