Distinguishing split supersymmetry in Higgs signals at the Large Hadron Collider
Sudhir Kumar Gupta, Biswarup Mukhopadhyaya, Santosh Kumar Rai
We examine the possibility of detecting signals of split supersymmetry in the loop-induced decay h --> gamma gamma of the Higgs boson at the Large Hadron Collider, where charginos,…
Bilarge neutrino mixing from supersymmetry with high-scale nonrenormalizable interactions
Biswarup Mukhopadhyaya, Probir Roy, Raghavendra Srikanth
We suggest a supersymmetric (SUSY) explanation of neutrino masses and mixing, where nonrenormalizable interactions in the hidden sector generate lepton number violating Majorana ma…
Associated single photons as signals for a doubly charged scalar at linear e-e- colliders
Biswarup Mukhopadhyaya, Santosh Kumar Rai
Doubly charged scalars, predicted in many models having exotic Higgs representations, can in general have lepton-number violating (LFV) couplings. The basis of most searches for th…
Invisible Higgs in large extra dimensions
Jari Laamanen
We discuss the possibility of detecting a Higgs boson in electron-positron collider experiments if large extra dimensions are realized in nature. In such a case, the Higgs boson ca…
Neutrino masses and lepton-number violation in the Littlest Higgs scenario
Tao Han, Heather E. Logan, Biswarup Mukhopadhyaya +1
We investigate the sources of neutrino mass generation in Little Higgs theories, by confining ourselves to the "Littlest Higgs" scenario. Our conclusion is that the most satisfacto…
Split supersymmetry and the role of a light fermion in a supergravity-based scenario
Biswarup Mukhopadhyaya, Soumitra SenGupta
We investigate split supersymmetry (SUSY) within a supergravity framework, where local SUSY is broken by the F-term of a hidden sector chiral superfield X. With reasonably general…
