Sentences with phrase «heavier than the proton»

If they exist, they are expected to be 15 orders of magnitude heavier than protons, and the energies needed to produce them are far beyond what any accelerator can reach.
Measured at the LHC to be more than 130 times heavier than the proton, the Higgs is one of the most massive particles known.
The note purported to show preliminary evidence for gamma rays from a decaying Higgs particle with a mass of about 115 gigaelectronvolts, some 115 times heavier than a proton.
Data collected during 2011 and 2012 at the Large Hadron Collider (LHC) at CERN in Switzerland, the world's highest - energy proton collider, has culminated in the discovery of a new particle that is about 135 times heavier than a proton.

Not exact matches

Pagels (1984) points out that if the relative masses of protons and neutrons were different by a small fraction of 1 per cent, making the proton heavier than the neutron, hydrogen atoms would be unstable since the protons that constitute their nuclei would spontaneously decay into neutrons.
Nobody knows how ultra — high - energy cosmic rays — mainly protons or heavier atomic nuclei — acquire energies millions of times higher than have been achieved with humanmade particle accelerators.
Two new looks at the gamma - ray sky suggest that if the mysterious matter is a particle, it is heavier than 40 gigaelectronvolts, about 44 times the mass of a proton.
Most elements heavier than uranium, which has 92 protons, do not exist stably in nature and must
More important, a convergence of observations suggests that cosmic neutrinos spring from the same astrophysical sources as other particles from space: highly energetic photons called gamma rays, and mysterious ultra-high energy cosmic rays — protons and heavier atomic nuclei that reach energies a million times higher than humans have achieved with particle accelerators.
Why are protons 2,000 times heavier than electrons, yet their charges are simply equal and opposite?
By using electron and positron beams instead of heavier protons, the ILC will allow physicists to probe particle properties with much greater precision than they can at the LHC.
Muons are about 200 times heavier than electrons, making them more sensitive to the proton's size.
So if the LHC coughs up new particles that are heavier than about 400 times the mass of a proton, then only a linear collider could make them, says Alain Blondel, a physicist at the University of Geneva.
Higher energy particles — such as those from the nuclei of heavy elements like iron — are rarer than common, lower - energy particles such as protons.
Elements heavier than uranium (with 92 protons), are not produced in nature but are made by scientists in labs.
«As already mentioned, there is no stable nucleus with five or eight nuclear particles [nucleons], so it is not possible to build nuclei heavier than helium by adding neutrons or protons to helium (4He) nuclei, or by fusing pairs of helium nuclei.
Remember, nuclei heavier than iron are so large that the strong force can barely hold on to their outer protons.
All elements heavier than iron were necessarily made by accretion of mostly neutrons but sometimes protons onto lighter nuclei.
