Kerr-Schild Geometry and Twistorial Structure of Spinning Particles
Alexander Ya. Burinskii · 2008
Spinning partir!t•s and twist.ors are traditional subjects of the string Lhrory anr the present. SQS-co11fcn!1H·c. Usual treatment concerns thr point.like (or st.ri11glikP) obj(!cl:S in (sup('.r)spac > rn. The corresponding source of the Kerr-Newman solution represents string-like structure which matches naturally with gravity and displays especial role of the Compton region. This space-time has twofold topology with a branch line along the Iforr singular ring which is a closed 'Alice' string. The field around the Kerr string is similar to the field around a heterotic string [l]. Polarization of the em-field near this string may be considered as em-excitation of the string. Structure of the Kerr-Schild geometry. The Kerr-Newman metric may be represented in the Kerr-Schild form
