The possibility of production of singlet Higgs particles coupling to exotic fermions at the CERN e+e- Collider LEP or the SLAC Linear Collider through the loop-induced decay Z0h0 is discussed and decay signatures for the singlet Higgs boson are suggested. It appears that singlet Higgs bosons may be detectable with 107 Z0's, if the unknown masses and couplings are in the right range. © 1991 The American Physical Society.

University of Calcutta (informally known as Calcutta University or CU) is a collegiate public state university located in Kolkata, West Bengal, India.&nbsp;Within India it is recognized as a &quot;Five-Star University&quot; and accredited &quot;A&quot; Grade by National Assessment and Accreditation Council.

&nbsp;

The University of Calcutta has secured the Fifth position among the Universities of India in the prestigious &quot;Indian University Ranking 2019&quot; list, released by the NIRF of the Ministry of Human Resource Development, Government of India.

It was established on 24 January 1857, and was one of the first institutions in Asia to be established as a multidisciplinary and Western-style university. Its alumni and faculty include several heads of state, heads of government, social reformers, prominent artists, only academy award winner and Dirac medal winner in India, many Fellows of the Royal Society and five Nobel laureates as of 2019 which is highest in South Asia.

Many extensions of the Standard Model include SU(2) L × U(1) Y singlet higgs bosons, h 0 , and also vector-like fermions which couple to it. The production and detection possibilities of such singlet neutral scalars at hadron colliders are considered for different scenarios of vectorlike fermions. We find that for some values of masses and couplings, detection at the CERN large hadron collider (LHC) appears to be a distinct possibility, while at the Fermilab Tevatron upgrade the h 0 might be observed only in very favourable circumstances. © Springer-Verlag 1996.
