Gravitational reheating in quintessential inflation
E. J. Chun, S. Scopel, I. Zaballa
We provide a detailed study of gravitational reheating in quintessential inflation generalizing previous analyses only available for the standard case when inflation is followed by…
Sparticle masses in deflected mirage mediation
Kiwoon Choi, Kwang Sik Jeong, Shuntaro Nakamura +2
We discuss the sparticle mass patterns that can be realized in deflected mirage mediation scenario of supersymmetry breaking, in which the moduli, anomaly, and gauge mediations all…
Dark matter and sub-GeV hidden U(1) in GMSB models
Eung Jin Chun, Jong-Chul Park
Motivated by the recent PAMELA and ATIC data, one is led to a scenario with heavy vector-like dark matter in association with a hidden sector below GeV scale. Realizing th…
Gauge-singlet dark matter in a left-right symmetric model with spontaneous CP violation
Wan-Lei Guo, Li-Ming Wang, Yue-Liang Wu +2
We propose a dark matter (DM) scenario in an extension of a left-right symmetric model with a gauge-singlet scalar field. The gauge-singlet scalar can automatically become a DM can…
Determining Spin through Quantum Azimuthal-Angle Correlations
Matthew R. Buckley, Seong Youl Choi, Kentarou Mawatari +1
Determining the spin of new particles is critical in identifying the true theory among various extensions of the Standard Model at the next generation of colliders. Quantum interfe…
Unparticles and electroweak symmetry breaking
Jong-Phil Lee
We investigate a scalar potential inspired by the unparticle sector for the electroweak symmetry breaking. The scalar potential contains the interaction between the standard model…
