Enriching the exploration of the mUED model with event shape variables at the CERN LHC
Amitava Datta, Anindya Datta, Sujoy Poddar
We propose a new search strategy based on the event shape variables for new physics models where the separations among the masses of the particles in the spectrum are small. Collid…
CP-violating Higgs at Tevatron
Siba Prasad Das, Amitava Datta, Manuel Drees
We analyze the prospect for observing the intermediate neutral Higgs () boson in its decay to two lighter Higgs bosons () at the Tevatron in the framework of the CP viola…
Are light sneutrinos buried in LEP data?
Amitava Datta, Aseshkrishna Datta
Supersymmetry may resolve the disagreement between the precision electroweak data and the direct limit on the higgs mass, if there are light sneutrinos in the mass range 55 GeV $ <…
LHC Signature of the Minimal SUGRA Model with a Large Soft Scalar Mass
Utpal Chattopadhyay, Amitava Datta, Anindya Datta +2
Thanks to the focus point phenomenon, it is quite {\it natural} for the minimal SUGRA model to have a large soft scalar mass m_0 > 1 TeV. A distinctive feature of this model is an…
Signatures of the Light Down-Squark Scenario at the Upgraded Tevatron
Amitava Datta, Shyamapada Maity, Anindya Datta
In scenarios with relatively light down squarks, motivated, e.g., by SO(10) D terms, jets + missing signals can be observed at the luminosity upgraded Tevatron even if the sq…
Effects of SO(10) D-Terms on SUSY Signals at the Tevatron
Amitava Datta, Aseshkrishna Datta, Manuel Drees +1
We study signals for the production of superparticles at the Tevatron in supergravity scenarios based on the Grand Unified group SO(10). The breaking of this group introduces extra…
Testing Gauge-Gravitino Coupling in Gauge-Mediated Supersymmetry Breaking Through Single Photon Events
Amitava Datta, Aseshkrishna Datta, Anirban Kundu +2
We show that the process missing energy, arising from the pair production of neutralinos, can probe the $γ-\tildeγ- \gravitino$ as well as the $Z-\tilde Z-\gravitin…
Virtual LSPs at e+ e- Colliders
Amitava Datta, Aseshkrishna Datta, Sreerup Raychaudhuri
Currently popular search strategies for supersymmetric particles may be significantly affected due to relatively light sneutrinos which decay dominantly into invisible channels. In…
Observing Virtual LSPs at LEP II
Amitava Datta, Aseshkrishna Datta, Sreerup Raychaudhuri
In the minimal supersymmetric extension of the Standard Model (MSSM) with -parity conservation the possibility that the sneutrino and the second lightest neutralino decay domina…
Probing Lepton Number Violation via Majorana Neutrinos at Hadron Supercolliders
A. Datta, M. Guchait, A. Pilaftsis
The possibility of discovering heavy Majorana neutrinos and lepton number violation via the like sign dilepton signal at hadron super- colliders is investigated. The cross-sections…
Prospect of Heavy Right-Handed Neutrino Search at SSC/LHC Energies
Amitava Dattta, Manoranjan Guchait, D. P. Roy
Right-handed neutrinos with large Majorana mass occur naturally in the left-right symmetric model. We explore the prospect of such heavy Right-handed Neutrino search Via deca…
Flavour Democracy Calls for the Fourth Generation
Amitava Datta
It is argued with the help of an illustrative model, that the inter--species hierarchy among the fermion masses and the quark mixing angles can be accommodated naturally in the sta…
