Abstract: | The transversity distribution of quarks in a nucleon is one of the three fundamental distributions, that characterize nucleon's
properties in hard scattering processes at leading twist (twist 2). It measures the distribution of quark transverse spin
in a nucleon polarized transverse to its (infinite) momentum. It is a chiral-odd twist-two distribution function — gluons
do not couple to it. Quarks in a nucleon/hadron are relativistically bound and transversity is a measure of the relativistic
nature of bound quarks in a nucleon. In this work, we review some important aspects of this less familiar distribution function
which has not been measured experimentally so far. |
