What does LHCb do?
LHCb is a special purpose experiment being prepared for the CERN LHC collider. Its primary aim is to investigate the decays of B-particles (particles containing b-quarks) and so provide insight into the phenomenon of matter-antimatter asymmetries.
What is the LHCb experiment at CERN?
The LHCb experiment is one of the four large experiments at the Large Hadron Collider at CERN, situated underground on the Franco-Swiss border near Geneva. The experiment is designed to study decays of particles containing a beauty quark, a fundamental particle that has roughly four times the mass of the proton.
What does LHCb stand for?
Large Hadron Collider beauty
The Large Hadron Collider beauty (LHCb) experiment specializes in investigating the slight differences between matter and antimatter by studying a type of particle called the “beauty quark”, or “b quark”.
What is Alice at CERN?
ALICE (A Large Ion Collider Experiment) is a detector dedicated to heavy-ion physics at the Large Hadron Collider (LHC). It is designed to study the physics of strongly interacting matter at extreme energy densities, where a phase of matter called quark-gluon plasma forms.
Who discovered Pentaquarks?
The name pentaquark was coined by Claude Gignoux et al. (1987) and Harry J. Lipkin in 1987; however, the possibility of five-quark particles was identified as early as 1964 when Murray Gell-Mann first postulated the existence of quarks.
When was the bottom quark discovered?
1977
In 1977, an experiment led by physicist and Nobel laureate Leon Lederman at Fermilab provided the first evidence for the existence of the bottom quark, an essential ingredient in the theoretical framework called the Standard Model.
What does the Alice experiment do?
Is the pentaquark real?
A pentaquark is a human-made subatomic particle, consisting of four quarks and one antiquark bound together; they are not known to occur naturally, or exist outside of experiments specifically carried out to create them.
Where are charm quarks found?
It was discovered in 1974 by a team at the Stanford Linear Accelerator Center (SLAC), led by Burton Richter, and one at the Brookhaven National Laboratory (BNL), led by Samuel Ting….Charm quark.

Why are bottom quarks called beauty?
The particles called beauty quarks are third-generation heavy quarks with exceptionally low transition rates to lower-mass quarks. The bottom quark is also notable because it is a product in almost all top quark decays and is a frequent decay product of the Higgs boson.
How hot does CERN get?
The Swiss Just Hit 5.5 Trillion Degrees In light of this summer’s record high temperatures, we find perspective on really hot temperatures. In an experiment, scientists at Europe’s CERN laboratory claim to have achieved the highest temperature ever produced by humans — about 5.5 trillion degrees.
What is rapidity in relativity?
In relativity, rapidity is commonly used as a measure for relativistic velocity. Mathematically, rapidity can be defined as the hyperbolic angle that differentiates two frames of reference in relative motion, each frame being associated with distance and time coordinates.
What is rapidity definition?
Definition of rapidity : the quality or state of being rapid.
What is LHCb detector?
The LHCb detector is a forward spectrometer at the Large Hadron Collider (LHC) at CERN. The experiment is designed for precision measurements of CP violation and rare decays of beauty and charm hadrons.
What is the LHCb experiment?
The LHCb experiment [1] is one of the four major experiments at the Large Hadron Collider (LHC) and is dedicated to the study of CP violation and the rare decays of heavy flavoured hadrons.
How does the LHCb detect b quarks?
To catch the b quarks, LHCb has developed sophisticated movable tracking detectors close to the path of the beams circling in the LHC. The 5600-tonne LHCb detector is made up of a forward spectrometer and planar detectors.
What is the Large Hadron Collider (LHCb)?
The LHCb experiment is situated at one of the four points around CERN’s Large Hadron Collider where beams of protons are smashed together, producing an array of different particles. How does it work? The aim of the LHCb experiment is to record the decay of particles containing b and anti-b quarks, collectively known as ‘B mesons’.
