I summarize here and discuss the results of presently operating neutrino telescopes in searching for a singnal of dark matter weakly interacting massive particles (WIMPs).

A natural explanation for the smallness of the neutrino mass requires them to be Majorana particles violating lepton number by two units. Since lepton number violation can have several interesting consequences in particle physics and cosmology, it is of utmost importance to find out if there is lepton number violation in nature and what is its magnitude. The neutrinoless double beta decay exper...

With almost 0.5 fb −1 of p¯ p-collisions delivered in Tevatron Run II, both experiments CDF and DØ are reporting first results from a vast number of search analyses. This article summarizes the current status of Tevatron searches for Higgs bosons within the Standard Model and its extensions as well as direct searches for supersymmetric particles. Signatures for production of squarks, gluinos, c...

At high temperatures or densities matter formed by strongly interacting elementary particles (hadronic matter) is expected to undergo a transition to a new form of matter the quark gluon plasma in which elementary particles (quarks and gluons) are no longer confined inside hadrons but are free to propagate in a thermal medium much larger in extent than the typical size of a hadron. The transiti...

I give a short review of the holographic approach to quantum gravity, with emphasis on its application to deriving the properties of elementary particles.

To embed the seesaw mechanism in the MSSM, two or three right-handed neutrino supermultiplets, Ni, have to be added to the model. In this framework, the supersymmetry breaking potential will include a new term called neutrino B-term: MBνÑÑ/2. In this talk, we present a toy model that generates a large neutrino B-term keeping other supersymmetry breaking parameters small. We then review the cons...

We derive the phase factor proposed by Beisert, Eden and Staudacher for the Smatrix of planar N = 4 Super Yang–Mills, from the all-loop Bethe ansatz equations without the dressing factor. We identify a configuration of the Bethe roots, from which the closed integral formula of the phase factor is reproduced in the thermodynamic limit. This suggests that our configuration describes the “physical...
