Welcome to the IDR @ NISER, Bhubaneswar
The NISER Institutional Repository has been created by the Central Library, NISER to showcase, organize, share, and preserve the scholarly output of National Institute of Science Education and Research, Bhubaneswar. The Repository is designed to facilitate scholarly communication by providing access to the knowledge resources created by NISER and preserving the same for future generations of scholars. This repository is running on Dspace, an open source software platform, and facilitates its users with advance searching and browsing options.

Measurements of the elliptic flow, v2, of identified hadrons (π±, K±, K0s, p, ¯p, ϕ, Λ, ¯¯¯Λ, Ξ−, ¯¯¯Ξ+, Ω−, ¯¯¯Ω+) in Au+Au collisions at √sNN=7.7, 11.5, 19.6, 27, 39, and 62.4 GeV are presented. The measurements were done at midrapidity using the time-projection chamber and the time-of-flight detectors of the Solenoidal Tracker at RHIC experiment during the beam-energy scan program at Relativistic Heavy Ion Collider. A significant difference in the v2 values for particles and the correspond...
A series of 4-bromonaphthalimide systems (BNI-Cn ; n = 4, 6, 10, 12, and 16) comprising different alkyl side chains have been synthesized and used as the building blocks to fabricate organic fluorescent micro materials. The systems have been developed basically to investigate the effect of alkyl side chains on the aggregation behavior of the systems. The aggregation behavior of these systems has been studied by spectroscopic and microscopic techniques. Microscopic investigation reveals that t...
We report measurements of the third harmonic coefficient of the azimuthal anisotropy, v3, known as triangular flow. The analysis is for charged particles in Au+Au collisions at √sNN=200 GeV, based on data from the STAR experiment at the BNL Relativistic Heavy Ion Collider. Two-particle correlations as a function of their pseudorapidity separation are fit with narrow and wide Gaussians. Measurements of triangular flow are extracted from the wide Gaussian, from two-particle cumulants with a pse...
Quantum pumping in graphene has been predicted in recent years. Till date there have been no experiments indicating a graphene based quantum pump. This is not uncommon as in the case of other non-Dirac behavior showing materials it has not yet been unambiguously experimentally detected. The reason is that in experiments with such materials the rectification effect overshadows the pumped current. In this work we answer the question posed in the title by taking recourse to “strain.” We show tha...
In this study, the publications of Odisha are collected from ISI Web of Science and quantitatively analysed. Total 14,899 items were retrieved for the period 1967-2011, and there was no publications available from 1945-1966. From 1972, the publications grow steadily up to 1982 but after that the growth is irregular, then rapidly growth is notices from 2006 onwards. Authors of State have collaborated with most of the developed countries of the world. It is a good sign that the publica...
The measurement of J/ψ azimuthal anisotropy is presented as a function of transverse momentum for different centralities in Au+Au collisions at √sNN=200 GeV. The measured J/ψ elliptic flow is consistent with zero within errors for transverse momentum between 2 and 10 GeV/c. Our measurement suggests that J/ψ particles with relatively large transverse momenta are not dominantly produced by coalescence from thermalized charm quarks, when comparing to model calculations.
Angular correlations between unidentified charged trigger particles and various species of charged associated particles (unidentified particles, pions, kaons, protons and antiprotons) are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV in the transverse-momentum range 0.3<pT<4 GeV/c. The correlations expressed as associated yield per trigger particle are obtained in the pseudorapidity range |ηlab|<0.8. Fourier coefficients are extracted...
We present the measurements of particle pair yields per trigger particle obtained from di-hadron azimuthal correlations in pp collisions at √s = 0.9, 2.76, and 7TeV recorded with the ALICE detector. The yields are studied as a function of the charged particle multiplicity. Taken together with the single particle yields the pair yields provide information about parton fragmentation at low transverse momenta, as well as on the contribution of multiple parton interactions to particle production....
The energy calibration and resolution of the electromagnetic calorimeter (ECAL) of the CMS detector have been determined using proton-proton collision data from LHC operation in 2010 and 2011 at a centre-of-mass energy of √s = 7 TeV with integrated luminosities of about 5\fbinv. Crucial aspects of detector operation, such as the environmental stability, alignment, and synchronization, are presented. The in-situ calibration procedures are discussed in detail and include the maintenance of the ...
