“…This class of models predicts the existence of heavy W R bosons, and there is a considerable body of work by Indians discussing collider signatures for these or closely related phenomena . Some gauge extensions, as well as a few recent 'anomalies' in the flavour sector seem to call for the existence of an extra U(1) symmetry and this predicts a heavy Z ′ boson, which has also been studied quite intensively by Indian theorists [781][782][783][784][785][786][787].…”

Indian scientists began to work on the theoretical aspects of LHC physics from the early 1980s, at the same time when the rest of the world started taking interest in this then-futuristic topic. From this point grew a whole school of collider phenomenologists, who now form a significant fraction of the Indian high-energy physics community. This article briefly reviews the growth and contributions of the Indian school, on the way describing some of the physics ideas while placing the work in the international context, and proceeding thus, brings the story up to date in mid-2022.Dedicated to the memory of the late D.P. Roy (1941Roy ( -2017, the father of Indian collider theory. The expectant 80sThe LHC owes its origin [1] to CERN's far-sighted leaders, Léon van Hove, who served from 1976-1980 as the Scientific Director-General, and Technical Director-General Sir John Adams (1976)(1977)(1978)(1979)(1980)(1981), who resolved that it would be feasible and scientifically rewarding to build the next-generation storage ring at CERN. Thus, in 1977, Adams wrote the crucial concept note that the LEP collider 1 tunnel, which would be excavated in the 1980s, should be made large enough to accommodate the superconducting magnets required for a future phase of proton acceleration at higher energies. This 1977 note may be thought of as the genesis of the LHC. By 1978, it was already well known in the community, even though the formal approval for the LEP came only in 1981, and the machine itself started running in 1989 [2]. However, the fact that the 20 TeV LHC would eventually come and that the physics at such a machine should be studied, was in the air right from the early 1980s onward. Moreover, the USA was supposed to build a 40 TeV Superconducting Super Collider (SSC) which, sadly, never materialised 2 . The 1980s were, in fact, a period of great optimism for high-energy physics -or, as it was then more commonly known, elementary particle physics. One trigger for this may have lain in the decision of the Nobel Prize committee, in 1979, to recognise the work of Glashow (1961) [3], of Salam (1966-1968 1 The Large Electron-Positron collider.2 It was sanctioned in 1989, and eventually cancelled in 1993.

We study the prospect of heavy singlet neutrinos as a dark matter (DM) candidate within a neutrinophilic U(1) model, where the Standard Model (SM) is extended with a U(1) gauge symmetry, and neutrino mass and oscillation parameters are explained through an inverse see-saw mechanism. The lightest of the heavy neutrinos plays the role of the DM, while the newly introduced scalars and the extra gauge boson $$Z'$$ Z ′ act as mediators between the dark sector and the SM sector. We show the range of model parameters where this DM candidate can be accommodated in the Weakly Interacting Massive Particle (WIMP) or Feebly Interacting Massive Particle (FIMP) scenario. The observed DM relic density (DMRD) is achieved via the new gauge boson and singlet scalar portals in the WIMP scenario, whereas within the FIMP scenario, these two particles assume a distinct yet pivotal role in generating the observed DMRD.
