Resumen
We investigate neutralino dark matter in supersymmetric flipped SU(5), focusing on candidates with masses of order 30–150 GeV and spin-independent cross-sections that are consistent with the most recent CDMS II results. We assume gravity mediated supersymmetry breaking and restrict the magnitude of the soft supersymmetry breaking mass parameters to 1 TeV or less. With non-universal soft gaugino and Higgs masses, and taking flipped SU(5) into account, we identify allowed regions of the parameter space and highlight some benchmark solutions including Higgs and sparticle spectroscopy.

Resumen
In this paper conformal hidden sectors of Ferrara–Zumino multiplets are investigated in framework of gravity mediation. The two-point correlator of Ferrara–Zumino multiplets can be parametrized, which implies the wave function renormalizations of components fields in gravity supermultiplet can be evaluated in relatively simple form. Soft terms are calculated via supercurrent approach. We find gaugino masses are independent of sfermion masses on general grounds. The unification of gaugino masses is not universal. In comparison with general gauge mediation, there are no sum rules for sfermion masses of each generation.

Resumen
We study constrained versions of the minimal supersymmetric model and investigate the hierarchy between the electroweak scale and the scale of superpartners that can be achieved without relying on specifying model parameters by more than one digit (or with better than 10% precision). This approach automatically avoids scenarios in which a large hierarchy is obtained by special choices of parameters and yet keeps scenarios that would otherwise be disfavored by various sensitivity measures. We consider models with universal gaugino and scalar masses, models with nonuniversal Higgs masses or nonuniversal gaugino masses and focus on scenarios in which all the model parameters are either of the same order or zero at the grand unification scale. We find that the maximal hierarchy between the electroweak scale and stop masses, requiring that model parameters are not specified beyond one digit, ranges from a factor of [Formula: see text][Formula: see text]10–30 for the CMSSM up to [Formula: see text][Formula: see text]300 for models with nonuniversal Higgs or gaugino masses.

Resumen
We consider the class of N = 1, d = 4 supergravity theories generated in the compactification of heterotic superstrings on asymmetric orbifolds. We study the dominant quadratic contribution to the 1-loop effective potential and find it to be negative. We also examine the mass term for the chiral fields and find that they are massless at the compactification scale. We show that it is possible to have models where, at the compactification scale, the cosmological constant, the gaugino masses and the masses for the chiral non-gauge singlet fields are all zero.

We have searched for R-parity violating supersymmetry in final states with electrons and muons, assuming a single non-zero LLĒ or [Formula: see text] coupling, in particular λ121, λ122 or λ′211. In the absence of an excess in the data, upper cross-section limits are set as a function of gaugino and slepton masses. The searches are performed on data collected with the DØ detector in Run II, at a center of mass energy of 1.96 TeV and an integrated luminosity of up to 240 pb-1. All limits are improving significantly compared to the DØ Run I results.

Resumen
We find that when two or more spanning clusters exist at the percolation threshold, the mass of each scales with the same fractal dimension D=1.89 in two dimensions and D=2.53 in three dimensions. We also determine the ratios of the masses of the spanning clusters. In two dimensions, this is done for different lattices of different shapes. In the case of two spanning clusters, the ratio of the larger spanning cluster to the smaller lies around 1.4 for two dimensions, almost independent of lattice structure and shape.

Resumen
We carry out an analysis of the non-universal supersymmetry breaking scalar masses arising in SO(10) supersymmetric unification. By considering patterns of squark and slepton masses, we derive a set of sum rules for the sfermion masses which are independent of the manner in which SO(10) breaks to the Standard Model gauge group via its SU(5) subgroups. The phenomenology arising from such non-universality is unaffected by the symmetry breaking pattern, so long as the breaking occurs via any of the SU(5) subgroups of the SO(10) group.

Resumen
Energy can be broadly classified into mass-based and non-mass-based. Therefore, thermodynamics is too broad and universal to interpret the complex phenomena within only matter. Here, we suggest that (1) the current mixed concept of energy and work can actually be expressed as the actions of non-masses and the actions of masses, respectively, and (2) the definition of total energy must be revised based on the product of temperature and entropy. These findings, i.e., that space contains energy and the current concept of temperature actually corresponds to space density, are validated by a reinterpretation of thermodynamics.

Resumen
We present the results of a deep, optical/IR wide field imaging survey of selected fields in the nearby (d~ 140 pc) Taurus star-forming region. We report the discovery of 9 new members with spectral types M5.75–M9.5. We derive an Initial Mass Function encompassing 54% of the known members in Taurus. Comparison with dense regions like the Trapezium Cluster in Orion shows that Taurus has produced x2 less brown dwarfs. We suggest that the lower frequency of brown dwarfs in Taurus may result from the low-density star-forming environment, leading to larger minimum Jeans masses.

Resumen
We study the properties of fundamental physical constants using the threefold classification of dimensional constants proposed by J.-M. Lévy-Leblond: constants of objects (masses, etc.), constants of phenomena (coupling constants), and “universal constants” (such as c and ℏ). We show that all of the known “natural” systems of units contain at least one non-universal constant. We discuss the possible consequences of such non-universality, e.g., the dependence of some of these systems on the number of spatial dimensions. In the search for a “fully universal” system of units, we propose a set of constants that consists of c, ℏ, and a length parameter and discuss its origins and the connection to the possible kinematic groups discovered by Lévy-Leblond and Bacry. Finally, we give some comments about the interpretation of these constants.

Resumen
Galaxy clusters are the endpoints of structure formation and are continuously growing through the merging and accretion of smaller structures. Numerical simulations predict that a fraction of their energy content is not yet thermalized, mainly in the form of kinetic motions (turbulence, bulk motions). Measuring the level of non-thermal pressure support is necessary to understand the processes leading to the virialization of the gas within the potential well of the main halo and to calibrate the biases in hydrostatic mass estimates. We present high-quality measurements of hydrostatic masses and intracluster gas fraction out to the virial radius for a sample of 13 nearby clusters with available XMM-Newton and Planck data. We compare our hydrostatic gas fractions with the expected universal gas fraction to constrain the level of non-thermal pressure support. We find that hydrostatic masses require little correction and infer a median non-thermal pressure fraction of ∼6% and ∼10% at R500 and R200, respectively. Our values are lower than the expectations of hydrodynamical simulations, possibly implying a faster thermalization of the gas. If instead we use the mass calibration adopted by the Planck team, we find that the gas fraction of massive local systems implies a mass bias 1 − b = 0.85 ± 0.05 for Sunyaev–Zeldovich-derived masses, with some evidence for a mass-dependent bias. Conversely, the high bias required to match Planck cosmic microwave background and cluster count cosmology is excluded by the data at high significance, unless the most massive halos are missing a substantial fraction of their baryons.
