Effective usage of e-resources
There is large quantity of subscribed e-resources which contain quality rich information in most of the technical institute libraries. In spite of advantages in terms of access and search capabilities, they are underused. Systematic plan has to be in place for their promotion of use. While a good ICT infrastructure is a prerequisite, it alone will not do. Proactive strategies are required and these need to be adopted imaginatively. Access to e-resources need to be made easier for both on campus and off campus users. Training will increase the confidence level of the users. Traditional awareness methods include: Personal visits, orientations, brochures, posters and displays. Newer technologies from the Web 2.0 such as RSS alert service, Blogs, Wikis and Face book make the interaction with the library not only interesting but also add more value
Jordan-Schwinger realizations of three-dimensional polynomial algebras
A three-dimensional polynomial algebra of order is defined by the
commutation relations ,
where is an -th order polynomial in
with the coefficients being constants or central elements of the algebra.
It is shown that two given mutually commuting polynomial algebras of orders
and can be combined to give two distinct -th order polynomial
algebras. This procedure follows from a generalization of the well known
Jordan-Schwinger method of construction of and algebras from
two mutually commuting boson algebras.Comment: 10 pages, LaTeX2
Unparticle physics in diphoton production at the CERN LHC
We have considered the di-photon production with unparticle at LHC. The
contributions of spin-0 and spin-2 unparticle to the di-photon production are
studied in the invariant mass and other kinematical distributions, along with
their dependencies on the model dependent parameters. The signal corresponding
to the unparticle is significant for moderate coupling constant values.Comment: 17 pages, 15 eps figure
Pseudo-scalar Higgs Boson Production at Threshold NLO and NLL QCD
We present the first results on the production of pseudo-scalar through gluon
fusion at the LHC to NLO in QCD taking into account only soft gluon
effects. We have used the effective Lagrangian that describes the coupling of
pseudo-scalar with the gluons in the large top quark mass limit. We have used
recently available quantities namely the three loop pseudo-scalar form factor
and the third order universal soft function in QCD to achieve this. Along with
the fixed order results, we also present the process dependent resummation
coefficient for threshold resummation to NLL in QCD. Phenomenological
impact of these threshold NLO corrections to pseudo-scalar production at
the LHC is presented and their role to reduce the renormalisation scale
dependence is demonstrated.Comment: 34 pages, 17 figure
