“…Several studies of split SUSY followed [280][281][282][283][284]. The impact of neutrino masses and mixings on SUSY models and corresponding collider signals was explored over the years in a series of papers [161,[285][286][287][288][289][290][291][292][293][294][295][296][297][298][299]. Another topic of interest was 'non-universal' SUSY models [292,[300][301][302][303][304][305], in addition to a collection of more purely phenomenological investigations [306][307][308][309][310][311][312][313][314][315][316][317][318], as the focus of the subject shifted away from UV-complete model building to the study of low-energy mass spectra.…”

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.

Minimal Supergravity Scalar Neutrino Dark Matter and Inverse Seesaw Neutrino Masses

We show that within the inverse seesaw mechanism for generating neutrino masses minimal supergravity is more likely to have a sneutrino as the lightest superparticle than the conventional neutralino. We also demonstrate that such schemes naturally reconcile the small neutrino masses with the correct relic sneutrino dark matter abundance and accessible direct detection rates in nuclear recoil experiments.
