LHCb experiment

LHCb is a particle-physics experiment at CERN’s Large Hadron Collider that studies particles containing bottom or charm quarks, including their decays and matter–antimatter differences.

LHCb detector: The forward spectrometer and detector systems built for the LHCb experiment at CERN. Its tracking, calorimetry, and particle-identification systems turn collisions into measurable decay signatures.
CP violation: A difference between the behavior of a physical process and its combined charge-conjugated and parity-reflected counterpart. LHCb measures CP-violating differences in decays of beauty and charm hadrons.
Large Hadron Collider: A particle accelerator at CERN that collides protons and heavy ions at high energies. LHCb operates at one of the LHC’s collision points and analyzes its proton-collision products.
ATLAS experiment: A general-purpose particle-physics experiment at the Large Hadron Collider. ATLAS covers a broad range of collision products, while LHCb specializes in forward heavy-flavour physics.
Quark: A fundamental particle that participates in the strong interaction and combines with other quarks to form hadrons. Bottom and charm quarks define the heavy-flavour particles central to LHCb’s program.
Forward spectrometer: A particle detector arranged to measure particles emerging close to a beam direction. LHCb uses forward geometry to capture particles produced predominantly along the proton beams.
B meson: A meson containing a bottom quark or antiquark paired with a lighter quark or antiquark. Beauty meson decays provide many of LHCb’s most sensitive tests of CP violation.
CERN: An international research organization operating major particle-physics facilities near Geneva. CERN built and operates the collider and laboratory infrastructure used by LHCb.
CMS experiment: A general-purpose particle-physics experiment at the Large Hadron Collider. CMS and LHCb offer complementary detector geometries and emphases in studying heavy-flavour processes.
Hadron: A composite particle made of quarks bound by the strong interaction. LHCb studies hadrons containing bottom or charm quarks and reconstructs their decay products.
