The Higgs itself has mass, and going by exclusion, researchers from the LHC and from its predecessor particle colliders were able narrow down the range of its value to between 115 and 140 giga — electron volts, or GeV.

Where a traditional accelerator can take kilometers to drive an electron to 50 giga - electron volts (GeV), Leemans and team showed that a mini-laser plasma accelerator could get electrons to 1 GeV in just three centimeters with a laser pulse of about 40 terawatt.
Physicists expect WIMPs to have a mass somewhere between 1 and 200 giga - electron volts (GeV)-- roughly between 1 and 200 times the mass of a proton — although in principle the mass could be higher.
This implies that the Higgs» «bare mass,» or starting value before other particles affect it, just so happens to be the negative of that astronomical number, resulting in a near - perfect cancellation that leaves just a hint of Higgs behind: 126 giga - electron - volts.
The Higgs boson has a mass of 126 giga - electron - volts, but interactions with the other known particles should add about 10,000,000,000,000,000,000 giga - electron - volts to its mass.
«What we see is that there a region between 120 and 160 GeV (giga - electron volts) where there is an excess,» CDF physicist Viviana Cavaliere of the University of Illinois at Urbana — Champaign explained to a packed Fermilab auditorium April 6.
(A giga -, or a billion, electron volts is a unit of particle mass or energy.)
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.
For the first time, RHIC is running at a record energy of 500 giga - electron volts (GeV) per collision, more than double the previous runs in which polarized proton beams collided at 200 GeV.
Physicists express the mass of subatomic particles in electron volts (eV) divided by the speed of light squared (c2) A giga - electron volt (GeV) is a billion electron volts, or about the mass of a proton.
