transverse mass

[trans¦vərs ′mas]
(relativity)
The ratio of a force acting on a relativistic particle in a direction perpendicular to its velocity to the resulting acceleration; equal to m0(1 -v 2/ c 2)-1/2, where m0 is the particle's rest mass, v is its speed, and c is the speed of light.

A similarity in the [R.sub.out]/[R.sub.side] ratio with transverse mass across the collision systems is found at the energy bridge from the SPS to RHIC.
These parameters include, but are not limited to, the specific reduced curvature of net-proton rapidity distribution [54-56], chemical freeze-out temperature [57, 58], mean transverse mass minus rest mass [57], yield ratios of positive kaons to pions [57-59], squared speed-of-sound [60], string tension in Schwinger mechanism [61], width and fraction of fragmentation source [62], and width ratios of experimental negative pion rapidity distribution to Landau hydrodynamic model prediction [58].
[m.sub.T] = [square root of [m.sup.2] + [p.sup.2.sub.T]] is the transverse mass of produced charged particle with rest mass m.
