Origin of brane cosmological constant in warped geometry models
Abstract
Space-time with warped geometry plays important role in ourunderstanding of many phenomenology and cosmological scenario inbraneworld models. The Randall-Sundrum model in this context wasoriginally formualated on flat branes.In this work I shall try to address the possible origin of non-zerocosmological constant on the visible brane from bulk as well as branedynamics which may lead to an accelerating universe.

Study of light (anti)-nuclei production in ALICE at the LHC
Space and time, with their vastness and eternity, are thetwo integral parts for dynamical description of nature.But what are their true characters?This talk will be a non-technical review of the evolutionof concepts of space and time over the years from Newton to Einstein toHawking — a journey of unveiling eternal mysteries.

Abstract
The $mu$-from-$u$ supersymmetric standard model ($muu$SSM)offers a solution to the $mu$-problem and simultaneously accommodatemassive neutrinos through $R$-parity violation and a TeV scale seesawusing a set of right-handed neutrino superfields. In this model a verylightneutralino can still decay inside the LHC detector through an availableeven lighter scalar/pseudoscalar state, with light neutralino $ o$ lighterscalar/pseudoscalar + neutrino decay mode. We emphasize how thisunique feature can be utilized to study a non-standard Higgs signal at theLHC,with Higgs $ o$ a pair of light neutralino decay mode.We demonstrate how $muu$SSM can manifest itself through events withdisplaced multileptons at the LHC and provides unique signature for themodel.
