Rapidity beam axis. The rapidity y is a generalization of velocity ¯L = pL/E: Rapidity II y is not Lorentz invariant, however, it has a simple transformation  2 Rapidities and Boosts · A rapidity will turn out to be analogous to an angle, and intimately related to velocity. · A boost is a change in rapidity, just as a rotation is a  15 Nov 2004 We see that the Lorentz transformations form a group, similar to the group of rotations, with the rapidity α being the (imaginary) rotation angle. First  in the laboratory system, a boost (Lorentz-transformation) can be applied, to find a It is simple to show that rapidity differences remain invariant under boosts  In the Lorentz transformation scenario, where Minkowski diagrams describe frames of reference, hyperbolic rotations move one frame to another.

A combination of two Lorentz boosts of speeds u and v in the same direction is a third Lorentz boost in the same direction, of speed (u + v)/(1 + uv/c²). Rapidity is a dimensionless quantity in special relativity defined as a function of the velocity. At low speeds, it is proportional to velocity, but at high speeds, rapidities still add, as opposed to velocity which requires a Lorentz transform to calculate. It is defined such that . Using rapidities, a Lorentz boost to a velocity has the simple form . This form makes it clear that a Lorentz Lorentz boost (x direction with rapidity ζ) \begin{align} ct' &= ct \cosh\zeta - x \sinh\zeta \\ x' &= x \cosh\zeta - ct \sinh\zeta \\ y' &= y \\ z' &= z \end{align} where ζ (lowercase zeta ) is a parameter called rapidity (many other symbols are used, including ϕ, φ, η, ψ, ξ ).

The infinitesimal Lorentz Transformation is given by: where this last term turns out to be antisymmetric (see problem 2.1) This last term could be: " A rotation of angle θ, where " A boost of rapidity η, where A Lorentz transformation is represented by a point together with an arrow, where the defines the boost direction, the boost rapidity, and the rotation following the boost.

Correspondingly, a Lorentz rotation imparts angular momentum. Both actions have a direction as well as a magnitude, and so they are vector quantities. They can be combined, and they can interact. II.2.

As stated at the end of section 11.2, the composition of two Lorentz transformations is again a Lorentz transformation, with a velocity boost given by the ‘relativistic addition’ equation (11.3.1) (you’re asked to prove this in problem 11.1). Lecture 7 - Rapidity and Pseudorapidity E. Daw March 23, 2012 Start with Equation 6 and perform a Lorentz boost on E=cand p z y0 = 1 2 ln E=c pz+ pz E=c E=c pz Viewed 6k times 4 We have derived the Lorentz boost matrix for a boost in the x-direction in class, in terms of rapidity which from Wikipedia is: Assume boost is along a direction ˆn = nxˆi + nyˆj + nzˆk, A Lorentz boost of (ct, x) with rapidity rho can be written in matrix form as (ct' x') = (cosh rho - sinh rho -sinh rho cosh rho) (ct x). A Lorentz boost of (ct, x) with rapidity p can be written in matrix form as (ct' x') = (cosh rho - sinh rho -sinh rho cosh rho) (ct x). Show that the composition of two Lorentz boosts - first from (ct, x) to (ct', x') with rapidity p_1, then from (ct', x') to (ct", x') with rapidity p_2 - is a Lorentz boost from (ct, x) to (ct", x") with rapidity rho = rho_1 + rho_2.
