A New Form Of Soft Supersymmetry Breaking?, Scott Chapman

Mathematics, Physics, and Computer Science Faculty Articles and Research

Starting with a supersymmetric U(N) × U(N) gauge theory built in N = 1 superspace, a nonsupersymmetric theory is obtained by “twisting” the gauginos into a different representation of the group than the gauge bosons. Despite the fact that this twisting breaks supersymmetry, it is still possible to construct an action that is holomorphic and invariant to local “twisted” gauge transformations in superspace. It is conjectured that these two properties may allow the theory to be free of quadratic divergences to all orders, despite a lack of supersymmetry. An explicit calculation shows that the theory is free of quadratic divergences …

Speculations On Brunelleschi’S Pazzi Chapel, Howard A. Risatti Professor Emeritus, Donald Schrader

Art Inquiries

Why speculate on Filippo Brunelleschi’s Pazzi Chapel? As Giorgio Vasari wrote, many of Brunelleschi’s projects were not finished in his lifetime and not as he wished. The lesson to be drawn, says Vasari, who was writing a century after Brunelleschi’s death, is that “anyone who wishes to leave a memorial of his existence should complete it in his own lifetime and not put faith in anyone else.” Since Brunelleschi died well before the chapel was completed, issues have been raised for over a century about its inconsistencies regarding the open loggia, the barrel-vaulted portico, and the façade. This paper addresses …
