Upper Limits on the Peccei-Quinn Scale and on the Reheating Temperature in Axino Dark Matter Scenarios
Ayres Freitas, Frank Daniel Steffen, Nurhana Tajuddin +1
Considering axino cold dark matter scenarios with a long-lived charged slepton, we study constraints on the Peccei-Quinn scale f_a and on the reheating temperature T_R imposed by t…
Astro Unparticle Physics
A. Freitas, D. Wyler
We investigate the effects of all flavor blind CP-conserving unparticle operators on 5th force experiments, stellar cooling, supernova explosions and compare the limits with each o…
Phenomenology of Mirror Fermions in the Littlest Higgs Model with T-Parity
A. Freitas, D. Wyler
Little Higgs models are an interesting alternative to explain electroweak symmetry breaking without fine-tuning. Supplemented with a discrete symmetry (T-parity) constraints from e…
A precise analytical description of the Earth matter effect on oscillations of low energy neutrinos
A. N. Ioannisian, N. A. Kazarian, A. Yu. Smirnov +1
We present a formalism for the matter effects in the Earth on low energy neutrino fluxes which is both accurate and has all advantages of a full analytic treatment. The oscillation…
Subleading collinear operators and their matrix elements
Andri Hardmeier, Enrico Lunghi, Dan Pirjol +1
We discuss the most general form of the leading power suppressed collinear operators in the soft-collinear effective theory. Such operators appear in the description of power corre…
Factorization in leptonic radiative B -> gamma eνdecays
Enrico Lunghi, Dan Pirjol, Daniel Wyler
We discuss factorization in exclusive radiative leptonic B->γeνdecays using the soft-collinear effective theory. The form factors describing these decays can be expanded in a power…
