Higgs Boson Mass, Sparticle Spectrum and Little Hierarchy Problem in Extended MSSM
We investigate the impact of TeV-scale matter belonging to complete
vectorlike multiplets of unified groups on the lightest Higgs boson in the
MSSM. We find that consistent with perturbative unification and electroweak
precision data the mass m_h can be as large as 160 GeV. These extended MSSM
models can also render the little hierarchy problem less severe, but only for
lower values of m_h < 125 GeV. We present estimates for the sparticle mass
spectrum in these models.Comment: 27 pages, 14 figure

Higgs Inflation, Quantum Smearing and the Tensor to Scalar Ratio
In cosmic inflation driven by a scalar gauge singlet field with a tree level
Higgs potential, the scalar to tensor ratio r is estimated to be larger than
0.036, provided the scalar spectral index n_s >= 0.96. We discuss quantum
smearing of these predictions arising from the inflaton couplings to other
particles such as GUT scalars, and show that these corrections can
significantly decrease r. However, for n_s >= 0.96, we obtain r >= 0.02 which
can be tested by the Planck satellite.Comment: 10 pages, 3 figures and 3 table

Oxidation of aliphatic alcohols by triethylammonium chlorochromate in non-aqueous medium – A kinetic and mechanistic study
AbstractThe oxidation of some aliphatic alcohols by triethylammonium chlorochromate (TriEACC) in dimethyl sulfoxide leads to the formation of the corresponding carbonyl compounds. The reaction is first order with respect to TriEACC. The reaction exhibited Michaelis–Menten type kinetics with respect to alcohol. The reaction is catalyzed by hydrogen ions. The hydrogen-ion dependence has the form: kobs=a+b[H+]. The oxidation of [1,1-2H2] ethanol (MeCD2OH) exhibits a substantial primary kinetic isotope effect. Oxidation of aliphatic alcohol was studied in 19 different organic solvents. The solvent effect has been analysed using Kamlet’s and Swain’s multi-parametric equation. A suitable mechanism has been proposed
