Complex Langevin study of spontaneous symmetry breaking in IKKT matrix model
Arpith Kumar, Anosh Joseph, Piyush Kumar
The IKKT matrix model, in the large- limit, is conjectured to be a non-perturbative definition of the ten-dimensional type IIB superstring theory. In this work, we investigate t…
Origins of Hidden Sector Dark Matter II: Collider Physics
Clifford Cheung, Gilly Elor, Lawrence J. Hall +1
We consider a broad class of supersymmetric theories in which dark matter (DM) is the lightest superpartner (LSP) of a hidden sector that couples very weakly to visible sector fiel…
The Leptonic Higgs as a Messenger of Dark Matter
Hock-Seng Goh, Lawrence J. Hall, Piyush Kumar
We propose that the leptonic cosmic ray signals seen by PAMELA and ATIC result from the annihilation or decay of dark matter particles via states of a leptonic Higgs doublet to …
Neutrino Masses, Baryon Asymmetry, Dark Matter and the Moduli Problem : A Complete Framework
Piyush Kumar
Recent developments in string theory have led to "realistic" string compactifications which lead to moduli stabilization while generating a hierarchy between the Electroweak and Pl…
Non-thermal Dark Matter and the Moduli Problem in String Frameworks
Bobby S. Acharya, Piyush Kumar, Konstantin Bobkov +3
We address the cosmological moduli/gravitino problems and the issue of too little thermal but excessive non-thermal dark matter from the decays of moduli. The main examples we stud…
The -MSSM - An Theory motivated model of Particle Physics
Bobby S. Acharya, Konstantin Bobkov, Gordon L. Kane +2
We continue our study of the low energy implications of theory vacua on manifolds, undertaken in \cite{Acharya:2007rc,Acharya:2006ia}, where it was shown that the moduli…
