What is transverse momentum in particle physics?
The transverse momentum of a particle is defined as , where and are the momentum components in the transverse momentum plane. The transverse momentum distributions of the final-state particles are called first observations in the high-energy experiments.
What is missing transverse momentum?
In a hadron collider event the missing transverse momentum is defined as the event momentum. imbalance in the plane transverse to the beam axis, where momentum conservation is expected. Such an imbalance may signal the presence of undetectable particles, such as neutrinos or new. stable, weakly-interacting particles.
What is transverse momenta?
In high energy particle physics, specifically in hadron-beam scattering experiments, the Transverse Momentum Distributions (TMDs) are the distributions of the hadron’s quark or gluon momenta that are perpendicular to the momentum transfer between the beam and the hadron.
What is transverse energy?
Transverse mass in two-particle systems Hadron collider physicists use another definition of transverse mass (and transverse energy), in the case of a decay into two particles. This is often used when one particle cannot be detected directly but is only indicated by missing transverse energy.
What is rapidity in special relativity?
From Wikipedia, the free encyclopedia. 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 are longitudinal and transverse masses?
The transverse mass is defined by electromagnetic force (Lorentz force) and the longitudinal mass is defined by electrostatic force.
What is rapidity and Pseudorapidity?
, pseudorapidity becomes equal to (true) rapidity. Rapidity is used to define a measure of angular separation between particles commonly used in particle physics , which is Lorentz invariant under a boost along the longitudinal (beam) direction.
What is PHI particle physics?
Phi (ɸ/φ) is the measurement of the azimuthal angle (or angle from the x-axis). Transverse momentum (PT) is the momentum perpendicular to the path of the colliding particles and is equal to Psin(θcm). Pseudorapidity is calculated from an xz-plane, with the z-axis being the particle beam.
Is transverse momentum Lorentz invariant?
The transverse momenta of visible decay products are invariant under Lorentz boosts of the parent rest frame along the beam direction.

What is longitudinal mass?
[‚län·jə′tüd·ən·əl ′mas] (relativity) The ratio of a force acting on a relativistic particle in the direction of its velocity to the resulting acceleration; equal to m0(1-v 2/ c 2)-3/2, where m0 is the particle’s rest mass, v is its speed, and c is the speed of light.
