Singlet GB contributions in the chiral constituent quark model
Harleen Dahiya, Manmohan Gupta, J. M. S. Rana
The implications of the latest data pertaining to \bar u-\bar d asymmetry and the spin polarization functions on the contributions of singlet Goldstone boson η' within \chiCQM with…
Octet magnetic moments and the violation of CGSR in QM with configuration mixing
Harleen Dahiya, Manmohan Gupta
Octet baryon magnetic moments are calculated within \chiQM, respecting color spin spin forces (Szczepaniak et al., PRL 87, 072001(2001)), incorporating the orbital angular momentum…
What is inside the nucleon?
Manmohan Gupta, Harleen Dahiya
We briefly review the structure of nucleon in the context of QCD, Constituent Quark Model and Chiral Quark Model.
Three flavor neutrino oscillations, LSND, SNP and ANP
Gulsheen Ahuja, Monika Randhawa, Manmohan Gupta
The recently reanalysed LSND data is investigated in the context of three flavor oscillations, with an emphasis on mass hierarchies and . The resultant mass hierarchies and…
Constructing "Reference" Triangle through Unitarity of CKM Matrix
Monika Randhawa, Manmohan Gupta
Motivated by the possibility of the low value of sin2βin the measurements of BABAR and BELLE collaborations, a reference unitarity triangle is constructed using the unitarity of th…
Implications of Configuration Mixing in The Chiral Quark Model With SU(3) and Axial U(1) Breakings for Nucleon Spin-Flavor Structure
Harleen Dahiya, Manmohan Gupta
The implications of Chiral Quark Model with SU(3) and axial U(1) symmetry breakings as well as configuration mixing generated by one gluon exchange forces (QM) are discu…
