deSitter vacua from uplifting D-terms in effective supergravities from realistic strings
A. Achucarro, B. de Carlos, J. A. Casas +1
We study the possibility of using the D-term associated to an anomalous U(1) for the uplifting of AdS vacua (to dS or Minkowski vacua) in effective supergravities arising from stri…
Some aspects of the phenomenology of canonical noncommutative spacetimes
Luisa Doplicher
I describe some phenomenological contexts in which it is possible to investigate effects induced by (string-motivated) canonical noncommutative spacetime. Due to the peculiar struc…
D-particles and the localization limit in quantum gravity
Giovanni Amelino-Camelia, Luisa Doplicher
Some recent studies of the properties of D-particles suggest that in string theory a rather conventional description of spacetime might be available up to scales that are significa…
Field Theories on Canonical and Lie-Algebra Noncommutative Spacetimes
Giovanni Amelino-Camelia, Michele Arzano, Luisa Doplicher
Field theories on canonical noncommutative spacetimes, which are being studied also in connection with string theory, and on -Minkowski spacetime, which is a popular example of…
Phenomenology of Particle Production and Propagation in String-Motivated Canonical Noncommutative Spacetime
Giovanni Amelino-Camelia, Luisa Doplicher, Soonkeon Nam +1
We outline a phenomenological programme for the search of effects induced by (string-motivated) canonical noncommutative spacetime. The tests we propose are based, in analogy with…
