Distinguishing between SUSY and Littlest Higgs Model using trileptons at the LHC
Littlest Higgs model with T-parity and Minimal Supersymmtric standard Model
with R-parity both give similar signatures in collider experiment with a huge
amount of missing energy depending upon mass of the lightest T-odd/R-odd
particle. In this talk, I will discuss possibility of distinguishing the two
models at the LHC in hadronically quiet signal where masses of R-odd particles
are identical to masses of T-odd particles.Comment: To appear in the proceedings of Supersymmetry and the Unification of

Quantum seals
A quantum seal is a way of encoding a message into quantum states, so that
anybody may read the message with little error, while authorized verifiers can
detect that the seal has been broken. We present a simple extension to the
Bechmann-Pasquinucci majority-voting scheme that is impervious to coherent
attacks, and further, encompasses sealing quantum messages by means of quantum
encryption. The scheme is relatively easy to implement, requiring neither
entanglement nor controlled operations during the state preparation, reading or
verification stages.Comment: To appear in Physica Scripta, 4 page
