Influence of collapsing matter on the enveloping expanding universe
Using a collapsing matter model at the center of an expanding universe as described by Weinberg we assume a special type of generated pressure. This pressure transmits into the surrounding expanding universe. Under certain restriction the ensuing hubble parameter is positive. The deacceleration parameter fluctuates with time, indicating that the universe accelerates for certain time and decelerates for other time intervals.

Accelerating Universe Around A Blackhole
We have assumed that in a physical universe a blackhole is created some where. We conjecture that this blackhole will then separate itself from the physical universe and will build up an extra dimensional entity associated with the physical universe. The extra dimensional entity we suppose to be orthogonal to the physical universe. We further conjecture that this blackhole is a Schwartzschild blackhole. We assume that this physical universe and the blackhole span a seven dimensional space with a common time coordinate. We then generate the Einstein equation. Using the time-blackhole and the time-time component of the equation we show that the Hubble parameter is positive and time dependent if we conjecture that both scale factor and the radius of the blackhole reduces exponetially. Under the same assumption we have also calculated the deacceleration parameter and shown that under certain constrain the universe accelerates.

The electroweak sector of the pMSSM in the light of LHC - 8 TeV and other data
A bstractUsing the chargino-neutralino and slepton search results from the LHC in conjunction with the WMAP/PLANCK and (g − 2)μ data, we constrain several generic pMSSM models with decoupled strongly interacting sparticles, heavier Higgs bosons and characterized by different hierarchies among the EW sparticles. We find that some of them are already under pressure and this number increases if bounds from direct detection experiments like LUX are taken into account, keeping in mind the associated uncertainties. The XENON1T experiment is likely to scrutinize the remaining models closely. Analysing models with heavy squarks, a light gluino along with widely different EW sectors, we show that the limits on mg˜$$ {m}_{\tilde{g}} $$ are not likely to be below 1.1 TeV, if a multichannel analysis of the LHC data is performed. Using this light gluino scenario we further illustrate that in future LHC experiments the models with different EW sectors can be distinguished from each other by the relative sizes of the n-leptons + m-jets + T signals for different choices of n.
