Abstract We construct rigid non-supersymmetric heterotic vacua with reduced rank and no tachyons in six and four dimensions. These configurations are based on asymmetric orbifold compactifications which do not admit neutral deformation moduli and rep

Abstract We construct new string vacua featuring Brane Supersymmetry Breaking, based on T 4/ℤ N orientifolds with O5+ planes and D 5 ¯ $$ \overline{\textrm{D}5} $$ branes. Differently from the original construction, in these vacua the cancellation

Abstract The landscape of six-dimensional supergravities is dramatically constrained by the cancellation of gauge and gravitational anomalies, but the full extent of its implications has not been uncovered. We explore the cancellation of global anoma

Abstract We extend the analysis of Misaligned Supersymmetry to orientifold vacua. The lack of modular invariance in the Klein bottle, annulus and Möbius strip amplitudes implies that the IR properties of the physical spectrum are related to the UV b

Abstract In a remarkable paper, Dienes discovered that the absence of physical tachyons in closed string theory is intimately related to oscillations in the net number of bosonic minus fermionic degrees of freedom, a pattern predicted by an underlyin

Catalogo della mostra presso il Museo Civico di Taverna, dal 25 marzo al 3 maggio 2015. Caravaggio in Calabria, durante la sua breve vita, non c'è mai stato; tanto meno ci sono opere sue. Arriva adesso, per la prima volta un suo capolavoro: il San G
Il progetto espositivo Roma/Seicento: verso il barocco, inaugurato a Pechino il 29 aprile presso il National Museum of China, è il secondo appuntamento che l'Italia onora nell'ambito della collaborazione bilaterale sottoscritta nel Memorandum d'inte
