Physicists with the CLEO collaboration have confirmed a decades-old prediction by observing a rare and extremely short-lived subatomic particle called charmed-strange meson. The particle decays into a proton and anti-neutron, producing about 10% of all collisions in the accelerator.
Burton Richter, a Nobel laureate in physics, has been awarded the 2007 AAAS Philip Hauge Abelson Prize for his outstanding contributions to research and public policy. The prize recognizes his work on energy and sustainable development, as well as his tireless advocacy for sound science in American government.
Physicists at RHIC have developed a way to measure subtle fluctuations in particle beams and send corrections ahead to smooth out scattering. This technique, called stochastic cooling, aims to recreate the conditions of the early universe, potentially saving time and money.
A new analysis reveals that predicted mass scale for discovering new particles is about one TeV, more than double the previous estimate. This discovery could revolutionize particle physics research.

Physicists at UCR have detected the top quark, the heaviest known elementary particle, for the first time without its antimatter partner, allowing them to study its properties and production process. The discovery has significant implications for understanding the fundamental nature of the universe and how objects acquire mass.
A global design team has made progress on the linear collider, which will explore energy regions beyond current particle accelerators. The project aims to answer questions about extra dimensions and the nature of the universe.
Ron Davidson, a professor at Princeton University, has received the 2005 Particle Accelerator Science and Technology Award for his contributions to the theory of charged particle beams. His work has applications in particle physics, nuclear physics, ion-beam-driven fusion, high energy density physics, and cancer therapy.
Physicists' theories on the top quark and weak nuclear force are challenged by a new measurement. The study suggests that the top quark is left-handed, contradicting previous theories linking it to the weak force.
An international team of scientists has successfully observed elusive neutrino oscillation using the Super-Kamiokande detector. The findings confirm that neutrinos have mass and change state from one type to another, providing evidence for neutrino mixing.
Willis developed liquid argon calorimetry, electron identification by detection of transition radiation, and hyperon beams. These innovations are now widely adopted in particle physics.
The SLAC experiment has discovered a new subatomic particle called the Ds (2317), which combines a charm quark with an anti-strange quark. This unusual configuration has unexpected properties that will provide insight into the force binding quarks together, challenging current understanding of quark forces.
Jacek Sekutowicz, a visiting senior scientist at Jefferson Lab, is leading the way in cavity redesign as part of a proposed 12 GeV upgrade. He and his colleagues aim to reduce or eliminate parasitic modes using high order mode couplers, resulting in highly efficient beam passage through the cavities.
Andrei Linde has been recognized with the Dirac Medal for his pioneering work in inflationary cosmology, which posits that the universe underwent a rapid expansion. His theory has already had notable observational successes and has become a paradigm for fundamental studies in cosmology.
A national consortium led by Cornell University is proposing a 20-mile-long linear collider to detect the Higgs boson and explore supersymmetry and antimatter. The collider would accelerate beams of electrons and positrons at high energies, providing fundamental details about the origin of the universe.
Physicists at Kansas State University are studying the top quark, the heaviest quark known, which is 40 times heavier than any other quark. They aim to understand its properties and relationship with other quarks to uncover why it doesn't exist naturally.
The National Science Foundation awards Cornell University $88 million to operate the Cornell Electron Storage Ring (CESR) accelerator for 54 months. The funding enables continued improvement of the facility for high-energy physics and X-ray research in various fields.
A new study by Prof. Mordechai Milgrom proposes a radical alternative to the existence of invisible dark matter, instead suggesting that modifications to Newton's laws are needed for giant galactic systems. The theory, known as MOdified Nonrelativistic Dynamics, could revolutionize our understanding of the universe.
