Limits on Associated Production of Visibly and Invisibly Decaying Higgs Bosons from Z Decays
F. De Campos, M. A. Garcia-JareÑO, Anjan S. Joshipura +3
Many extensions of the standard electroweak model Higgs sector suggest that the main Higgs decay channel is "invisible", for example, where denotes the majoron, a w…
Fragmentation contribution to quarkonium production in hadron collision
D. P. Roy, K. Sridhar
We compute the contributions due to gluon and heavy-quark fragmentation to quarkonium production at large transverse momentum in and collisions. For inclusive $J/ψ…
Mass Limits of Invisibly Decaying Higgs Particles from the LEP Data
Biswajoy Brahmachari, Anjan S. Joshipura, Saurabh D. Rindani +2
In the Majoron models the doublet Higgs can decay invisibly into a Majoron pair via its mixing with a singlet. An analysis of the LEP data shows the invisible decay mode to…
Tevatron Mass Limits for Heavy Quarks Decaying via Flavor Changing Neutral Current
Biswarup Mukhopadhyaya, D. P. Roy
The dimuon and dielectron data from the Tevatron collider are used to probe for heavy quarks, which decay dominantly via flavour changing neutral current. Depending on wh…
