Heavy Quarkonium Potential Model and the State of Charmonium
A theoretical explanation of the observed splittings among the P~states of
charmonium is given with the use of a nonsingular potential model for heavy
quarkonia. We also show that the recently observed mass difference between the
center of gravity of the states and the state of
does not provide a direct test of the color hyperfine interaction in heavy
quarkonia. Our theoretical value for the mass of the state is in
agreement with the experimental result, and its E1 transition width is
341.8~keV. The mass of the state is predicted to be 3622.3~MeV.Comment: 15 page REVTEX documen
BSM Primary Effects: The complete set of predictions from the dimension-6 BSM Lagrangian
We present a physical parameterization of the leading effects beyond the SM
(BSM), that give us, at present, the best way to constrain heavy new-physics at
low-energies. We call these effects that constrain all possible interactions at
the dimension 6 level, BSM Primary effects; there are 8 primaries related to
Higgs physics, 3 related to Triple Gauge Couplings and 7 related to Z- pole
measurements at LEP. Starting from these experimentally measurable deformations
(and not operators), we construct the dimension 6 Lagrangian in a bottom up
way. We, thus, show that other BSM effects are not independent from the primary
ones and we provide the explicit correlations. We also discuss the theoretical
expectation for the size of these BSM primaries in some well-motivated BSM
theories.Comment: Based on talk given at DIS 2014. This talk was completely based on

Signature of strong atom-cavity interaction on critical coupling
We study a critically coupled cavity doped with resonant atoms with
metamaterial slabs as mirrors. We show how resonant atom-cavity interaction can
lead to a splitting of the critical coupling dip. The results are explained in
terms of the frequency and lifetime splitting of the coupled system.Comment: 8 pages, 5 figure
Comparison of the Effects of Coconut Oil and Soyabean Oil on TSH Level and Weight Gain in Rabbits
The present study was conducted on 12 albino rabbits of either sex and weighing between 1-1.5kg to see the influence of coconut oil and soyabean oil on serum TSH levels and weight gain for a period of 12 weeks. The rabbits were divided into 2 groups of six each. Rabbits in group 1 were fed on coconut oil and in group 2 were fed on soyabean oil in addition to their standard diet. At the end of 12 weeks we found that rabbits fed on soyabean oil had significant increase in TSH levels (p= 0.003) and gained more weight (p=0.000) when compared to rabbits fed on coconut oil
Bc spectroscopy in a quantum-chromodynamic potential model
We have investigated spectroscopy with the use of a
quantum-chromodynamic potential model which was recently used by us for the
light-heavy quarkonia. We give our predictions for the energy levels and the
1 transition widths. We also find, rather surprisingly, that although
is not a light-heavy system, the heavy quark effective theory with the
inclusion of the and corrections is as successful
for as it is for and .Comment: 10 page ReVTeX pape
