Sea contribution to the charge radii and quadrupole moment of baryons
Preeti Bhall, Meenakshi Batra, Alka Upadhyay
An operator formalism is used on the wavefunction of baryons to compute their charge radii and quadrupole moments. Total anti-symmetric wavefunction in spin, color and flavor space…
Importance of Non-Perturbative QCD Parameters for Bottom Mesons
A. Upadhyay, M. Batra
The importance of non-perturbative Quantum Chromodynamics [QCD] parameters is discussed in context to the predicting power for bottom meson masses and isospin splitting. In the fra…
Strong Decay widths and Coupling Constant of Recent Charm Meson States
Meenakshi Batra, Alka Upadhyay
Using an effective Lagrangian approach based on heavy quark symmetry and chiral dynamics, we explore the strong decay widths and branching ratios of various resonances and suggest…
B-meson spectroscopy in heavy hadron chiral perturbation theory
A. Upadhyay, M. Batra
The theory of heavy meson masses, in which the symmetries of heavy and light quarks are exploited, can be used to describe the low energy interaction among heavy mesons to a better…
Octet magnetic Moments and their sum rules in statistical model
M. Batra, A. Upadhyay
The statistical model is implemented to find the magnetic moments of all octet baryons. The well-known sum rules like GMO and CG sum rules has been checked in order to check the co…
Strange Mass Corrections to Hyperonic Semi-leptonic Decay in Statistical Model
A. Upadhyay, M. Batra
The spin distributions, weak decay matrix elements for strange baryon octets with SU(3) breaking effects is studied. We systematically apply operator formalism along with statistic…
Sea Quark and Gluon contributions to Strange Baryons and their Properties
M. Batra, A. Upadhyay
We treat the hadrons as an ensemble of quark-gluon Fock states where contributions from sea-quarks and gluons can be studied in detail for the properties of low lying baryons. Stat…
Heavy-light charm mesons spectroscopy and decay widths
Alka Upadhyay, Meenakshi Batra, Pallavi Gupta
We present the mass formula for heavy-light charm meson for one loop, using heavy quark effective theory. Formulating an effective Lagrangian, the masses of the ground state heavy…
Strange and nonstrange sea quark-gluon effects in nucleons
M. Batra, A. Upadhyay
Probabilities of various Fock states with strange and nonstrange quark-gluon sea contents are calculated to probe the hadronic structure. Particularly for nucleon, we find various…
Detailed Balance and Spin Content of Λ using Statistical Model
M. Batra, A. Upadhyay
In this study, we assume the hadrons as an ensemble of quark-gluon Fock states and apply statistical effects to explain the spin distribution of quarks for lambda hyperon. We exten…
Importance of Sea Contribution to Nucleons
M. Batra, A. Upadhyay
We studied the statistical model of nucleons consisting of sea having various quark-gluon Fock states in addition to valence quarks. Using statistical consideration and taking 86%…
Phenomenology of neutrino mixing in vacuum and matter
A. Upadhyay, M. Batra
Neutrino oscillation is the new physics beyond standard model. In this paper we have revisited the issue of neutrino oscillation in simple and delicate manner. Starting from the fu…
Heavy quark effective theory for charmed mesons
S. Singh, M. Batra, A. Upadhyay
Within the framework of heavy quark effective theory and chiral perturbation theory, masses and splittings of heavy charm mesons are studied. A mass formula is used for comprehensi…
Scalar and Tensor Sea Contributions to Nucleons
M. Batra, A. Upadhyay
Statistical approach for proton and neutron have been used to study the low energy properties of nucleons. Nucleons is assumed as a composite system of three quarks and "sea" where…
