A positron is the antimatter equivalent of an electron. Like an electron, a positron has an extremely low mass, and has a spin of...
FDG is a positron emitter, with the emitted positron being annihilated and producing two photons detected by the ring of detectors in the PET scanner. The PET is done together with a CT scan, which is used for both anatomic localization and attenuation correction. FDG is selectively taken up ...

What is Atomic Theory? What is Antimatter? What is a Positron? What is a Cloud Chamber? Discussion Comments By anon945919 — On Apr 15, 2014 If neutrinos are so difficult to detect, then how do they know that the collision of an electron and a positron does not result in an explosion...
In Oceanography, what is Alvin? What is a Positron? Discussion Comments By Perdido — On Apr 26, 2012 I didn't know that archaeologists could use tomography to protect their artifacts. That is an awesome tool to have when you are working with items that are thousands of years old. I...
A positron is an antimatter counterpart of the electron with a positive charge. A proton is a baryon particle found in the nucleus of atoms with a positive charge.

But if there really is a deficit in the WW channel, it could suggest that the new particle might not be a scalar boson with zero spin. “The WW search is designed to look for a spin-0 [scalar] particle,” admits Bill Murray, who is a member of the ATLAS collaboration. “They have...
Positron emission tomography (PET scan) uses a radioactive drug, which is injected into a vein and collects in areas of the body where cancer may be located. Computed tomography (CT scan) uses X-rays rotated around your body that give a 3D image with more detail than a standard X-ray....
