We derive the extended Supersymmetric Galilean Conformal Algebra (SGCA) in two spacetime dimensions by the method of group contraction on 2d  n id="mmlsi1" class="mathmlsrc">n class="formulatext stixSupport mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0370269316000435&_mathId=si1.gif&_user=111111111&_pii=S0370269316000435&_rdoc=1&_issn=03702693&md5=6fd6ab9271bae2443df1b82a44be27f3" title="Click to view the MathML source">N=(2,2)n>n class="mathContainer hidden">n class="mathCode">2n>,n>2n>)n>n>n> superconformal algebra. Both the parent and daughter algebras are infinite-dimensional. We provide the representation theory of the algebra. We adopt a superspace formalism for the SGCA fields, allowing us to write them down in a compact notation as components of superfields. We also discuss correlation functions, short supermultiplets and null states.
