electron-positron pair

"It's very easy for me to imagine enough energy to come up with an electron-positron pair."

Consider a virtual electron-positron pair produced just outside the event horizon.

Real photons spend part of their time (about a) as a virtual electron-positron pair.

After that, the number of electron-positron pairs decreased rapidly.

The emulsions were later scanned for electron–positron pairs.

For example, neutrinos should exhibit Bremsstrahlung in the form of electron-positron pair production.

Some of these may decay into simpler particles and eventually into electron-positron pairs.

Can an intense laser rip photons into electron-positron pairs?

This can happen when the core of a massive main-sequence star becomes hot enough to generate electron-positron pairs.

Because of this, pulsars can create and accelerate electron-positron pairs, ejecting them into space at almost light speed.

So many high-energy gamma rays are created that some literally turn from energy to mass in the form of an electron-positron pair.

Photons hit thin metal sheets, converting to electron-positron pairs, via a process known as pair production.

The equations may also need modifications to account for pair production of electron-positron pairs (or other particles at the highest temperatures).

He offers technical data showing the plausibility of an original super massive relativistic electron-positron pair.

This includes paths that involve highly improbable events like electron-positron pairs appearing out of nowhere, and disappearing again.

The spark chamber was used to induce a process called electron-positron pair production as a gamma ray entered the telescope.

Gamma rays produced by stars of fewer than 100 or so solar masses are not energetic enough to produce electron-positron pairs.

Furthermore, the momentum density of annihilating electron-positron pairs is enhanced near the Fermi surface.

The anomalous gamma-ray behavior was eventually ascribed to electron-positron pair production and annihilation.

The time the photon's energy spends as subluminal electron-positron pairs lowers the observed speed of light in a vacuum.

Figure 7.2 When an electron-positron pair is made out of gamma radiation, the positron may annihilate with a different electron, leaving its original partner free.

Quantum fluctuations allow for the creation of virtual electron-positron pairs with a lifetime estimated by the uncertainty principle .

For example, a dressed electron include the chaotic dynamics of electron-positron pairs and photons surrounding the original electron.

Its detector operated on the principle of electron-positron pair production from high energy photons interacting in the detector.

From Einstein's equation , gamma rays must have more energy than the mass of the electron-positron pairs to produce these pairs.
