Top polarization, forward-backward asymmetry and new physics
Debajyoti Choudhury, Rohini M. Godbole, Saurabh D. Rindani +1
We consider how the measurement of top polarization at the Tevatron can be used to characterise and discriminate among different new physics models that have been suggested to expl…
The Extended Higgs System in -symmetric Supersymmetry Theories
S. Y. Choi, D. Choudhury, A. Freitas +2
The Higgs sector is extended in -symmetric supersymmetry theories by two iso-doublets which complement the standard iso-doublets . We have analyzed masses and…
A fourth generation, anomalous like-sign dimuon charge asymmetry and the LHC
Debajyoti Choudhury, Dilip Kumar Ghosh
A fourth chiral generation, with in the range GeV and a moderate value of the CP-violating phase can explain the anomalous like-sign dimuon charge…
Mutual consistency of the MINOS and MiniBooNE Antineutrino Results and Possible CPT Violation
Debajyoti Choudhury, Anindya Datta, Anirban Kundu
Discussing the recent MINOS data on muon anti-neutrino disappearance and the MiniBooNE data on muon anti-neutrino to electron anti-neutrino oscillation, we show that the while the…
Dirac Neutralinos and Electroweak Scalar Bosons of N=1/N=2 Hybrid Supersymmetry at Colliders
S. Y. Choi, D. Choudhury, A. Freitas +3
In the N=1 supersymmetric extension of the Standard Model, neutralinos associated in supermultiplets with the neutral electroweak gauge and Higgs bosons are, as well as gluinos, Ma…
