Tomographic Studies of the sQGP at RHIC
Azimuthal correlation functions are used to study jetand di-jet properties as a function of centrality in Au+Au collisions at √ s NN =200 GeV. Utilizing a novel technique to decompose the correlation function into a (di-)jet and an underlying event, the jet-pair distribution is extracted and compared to similar results for d+Au collisions obtained at the same collision energy. A striking simila...
متن کاملMultiparticle angular correlations: a probe for the sQGP at RHIC
A novel decomposition technique is used to extract the centrality dependence of di-jet properties and yields from azimuthal correlation functions obtained in Au+Au collisions at √ s NN =200 GeV. The width of the near-side jet shows very little dependence on centrality. In contrast, the away-side jet indicates substantial broadening as well as hints for for a local minimum at ∆φ = π for central ...
متن کاملSparticles at the LHC
Sparticle mass hierarchies will play an important role in the type of signatures that will be visible at the Large Hadron Collider. We analyze these hierarchies for the four lightest sparticles for a general class of supergravity unified models including nonuniversalities in the soft breaking sector. It is shown that out of nearly 104 possibilities of sparticle mass hierarchies, only a small nu...
متن کاملOctetonium at the LHC
Several models of new physics, such as grand unified theories, Pati-Salam models, chiral color models, etc., predict the existence of an SU(2)L doublet of color-octet scalars (COS). In the Manohar-Wise model, the Yukawa couplings of the COS are assumed to be consistent with Minimal Flavor Violation ensuring constraints from flavor physics are satisfied even for relatively light scalars. In this...

We speculate about a heavy bottom-charm six-quark baryon. A semiclassical and a gaussian estimate reveal that the octet-octet bbb-ccc configuration can be energetically favored with respect to the singlet-singlet one. This result suggests that a confined bbb-ccc six-quark state may exist. Such objects may be produced in appreciable amount in heavy ion collisions at LHC energies.
