Sentences with phrase «mass than an electron»

Not exact matches

By this he means an energy project that could produce electrons for the grid in mass quantity, as opposed to something clever that barely generates more energy than you put in to build it.

In July, the physicists of the LHC experiments announced that whilst the Higgs boson had not yet been discovered, they were specifying tighter limits upon what its mass could be - which is about 300,000 times less than that of the electron!

Last year a team at University College London used the clustering of galaxies as a proxy for the clumping of matter, and their result put that mass at under 0.28 electronvolts, less than one - millionth the mass of an electron.

After all, particle accelerator searches over the last two decades had narrowed the range of possible masses for the Higgs; if it existed at all, it had to weigh in at between 114 billion and 143 billion electron volts or GeV (1 GeV is slightly more than the mass of a hydrogen atom).

In fact, the force exerted on the electrons is considerably larger than that occurring around a typical astrophysical black hole of ten solar masses.

KATRIN will study neutrinos, which are less than a millionth the mass of an electron, by sifting through the aftermath of radioactive decays of tritium, an isotope of hydrogen with two neutrons.

That fact suggests that the particles must be more massive than about 0.3 billion electron volts — about a third the mass of a proton — the researchers calculate.

The exchange lists more than 1000 experts in techniques including sequencing, electron microscopy and mass spectrometry.

Although the exact masses remain unknown, researchers estimate neutrinos to be two million times lighter than the next heavier particle, the electron, and this large mass difference is one of the great puzzles of neutrino physics.

As these neutrinos pass through the planet, they interact with atoms, creating muons — positive or negative particles with a mass much greater than an electron's.

Despite existing in a solid and being surrounded by atoms, these electrons can sometimes behave just like free electrons, albeit with an «effective mass» that may be different than the free electron mass.

Specifically, Nambu's work describes how these fundamental forces can be so different, and how elementary particles, including the particles that mediate those forces, can have such disparate masses — according to the Nobel committee, the top quark is more than 300,000 times heavier than the electron, whereas the photon has no mass at all.

The measured mass of electrons in solids is always larger than the value predicted by theory.

«If there is a Higgs boson whose mass is less than that of the Z particle, physicists will discover it over the next two years at the large accelerator in Geneva known as LEP (the Large Electron Positron collider).

In addition to the electron (and it's anti-particle, the positron), the charged leptons include the muon (with a mass 200 times greater than that of the electron), the tau (with mass 3,500 times greater than that of the electron) and their anti-particles.

Slamming protons and antiprotons together at 40 tera - electron volts (40 trillion eV), the SSC would have put out more than enough energy to create the elusive Higgs boson, sometimes called the «God particle,» which gives other particles their mass.

This object, with a mass of 2.7 x 10 - 24 kg, is over a million times more massive than a single electron (10 - 30 kg).

The technique consists of breaking down the atoms or molecules in a sample so that they become charged with more or fewer electrons than the original (ionization) and then separating them by mass / charge ratio in order to identify and quantify them.

Previous collider experiments had placed a lower bound of 114 giga - electron volts (GeV), a measure that can be used for particle mass, on the Higgs, and theoretical calculations require it to be less than 185 GeV.

Because the ease with which one neutrino oscillates into another is related to the difference in those particles» masses, a suitably heavy sterile neutrino could explain the greater than expected number of electron antineutrinos.

For more than three decades, physicists have been looking for, well, next to nothingelementary particles of matter called electron - neutrinos that have no charge and practically no mass.

If the remaining mass of the core is less than 1.4 solar masses, the pressure from the degenerate electrons (called electron degeneracy pressure) is enough to prevent further collapse.

Using a low - mass radial compressor wheel, the electron - powered supercharger spools up in less than 0.3 seconds to 70,000 rpm, helping the engine achieve maximum torque quickly.
