Scientists at Gran Sasso needed the cerium for a search — now called off —
for hypothetical particles called sterile neutrinos.
SOLE POLE Scientists are searching
for hypothetical particles called magnetic monopoles, which have a single north or south magnetic pole.
By picking particular masses
for the hypothetical particles, the researchers were able to calculate the number and sizes of clumps that could be floating through the Milky Way.
Not exact matches
The main contender
for the substance is a type of
hypothetical particle known as a «weakly interacting massive
particle» (WIMP).
When women routinely win Nobel Prizes in physics, chemistry or medicine, when a woman becomes a world chess champion, when a woman conceives and develops a brand new computer chip that represents a significant advancement over quad cores, when a woman invents warp drive or phasers, when a woman solves an «insolvable» math problem, when a woman, while working with the Large Hadron Collider, discovers the now -
hypothetical Higgs Boson to be an actual scalar subatomic
particle, when a woman figures out how to pinpoint the exact location of an electron at any point in time, when a woman working
for Merck or Pfizer develops a remedy
for Alzheimer's disease, when a woman's baseball team can defeat the New York Yankees, when a woman can bench press six hundred pounds, run the 100 meter dash in under nine seconds or set a world record in the high jump, then the fairer sex will have made an advance or contribution unlike any it has made before.
For the first time, physicists are snooping on some of the likeliest hiding places for hypothetical subatomic particles called axions, which could make up dark matt
For the first time, physicists are snooping on some of the likeliest hiding places
for hypothetical subatomic particles called axions, which could make up dark matt
for hypothetical subatomic
particles called axions, which could make up dark matter.
The LHC has just the right energy to search
for a
hypothetical dark
particle called a WIMP, or weakly interacting massive
particle.
The
particle looks an awful lot like the long - sought, and long -
hypothetical, Higgs boson, most famous
for explaining why elementary
particles, such as quarks, have mass.
These enigmatic,
hypothetical particles are the leading suspects in the search
for dark matter, the unseen bits of whatever that are thought to make up the bulk of the matter in the universe.
Physicists will observe the collisions not only
for clues to fundamental constituents of matter, hidden dimensions, and the elusive Higgs boson — the
hypothetical particle that gives matter its heft — but also
for tiny black holes winking in and out of existence.
One major ingredient in this model is a
hypothetical, ubiquitous quantum field that is supposed to be responsible
for giving
particles their masses (this field would answer the basic question of why
particles have the masses they do — or indeed, why they have any mass at all).
For example, in 2008 Jonathan Feng and Jason Kumar, both then at the University of California, Irvine, showed how a phenomenon known as supersymmetry could produce a
hypothetical class of
particles much lighter and more weakly interacting than WIMPs.
Nevertheless, by calculating the mass of that
hypothetical parent
particle, researchers were able to test
for different combinations of spin and parity by proxy.
It uses a variety of tools including VERITAS, AUGER and COUPP — dedicated telescopes, water tanks and underground «bubble chambers» — to observe known
particles and to search
for those that are so far only
hypothetical, such as the dark - matter WIMPs (weakly interacting massive
particles).
Massive gravity,
for example — a theory of gravity that assigns a mass to a
hypothetical elementary
particle called a graviton — still holds a sliver of possibility if the graviton has a very slight mass.
