Abstract

In this paper, we give an algebraic construction of a new infinite family of Cameron-Liebler line classes with parameter x=q212x=\frac{q^2-1}{2} for q5q\equiv 5 or 9(mod12)9\pmod{12}, which generalizes the examples found by Rodgers in \cite{rodgers} through a computer search. Furthermore, in the case where qq is an even power of 33, we construct the first infinite family of affine two-intersection sets in AG(2,q)\mathrm{AG}(2,q).
