Future Direction Beyond the Standard Theory
/ Pomarol, Alex (Barcelona, Autonoma U.)
With the Higgs discovery, the full Standard Model (SM) has been experimentally established, and most of its sectors accurately tested. Nevertheless, the SM deeply relies in the presence of the Higgs, a spin-zero field, whose mass term is not expected, on theoretical grounds, to be much smaller than the Planck scale. [...]

The Higgs Boson Search and Discovery
/ Bernardi, Gregorio (Paris U., VI-VII) ; Konigsberg, Jacobo (Florida U.)
We present a brief account of the search for the Higgs boson at the three major colliders that have operated over the last three decades: LEP, the Tevatron, and the LHC. The experimental challenges encountered stemmed from the distinct event phenomenology as determined by the colliders energy and the possible values for the Higgs boson mass, and from the capability of these colliders to deliver as much collision data as possible to fully explore the mass spectrum within their reach. [...]

A Historical Profile of the Higgs Boson
/ Ellis, John (King's Coll. London ; CERN) ; Gaillard, Mary K (LBL, Berkeley) ; Nanopoulos, V (Texas A-M ; Athens Academy)
The Higgs boson was postulated in 1964, and phenomenological studies of its possible production and decays started in the early 1970s, followed by studies of its possible production in e+ e−, and pp collisions, in particular. Until recently, the most sensitive searches for the Higgs boson were at LEP between 1989 and 2000, which were complemented by searches at the Fermilab Tevatron. [...]

Global Fits of the Electroweak Standard Theory: Past, Present and Future
/ Baak, M (CERN) ; Haller, J (Hamburg U.) ; Mönig, K (DESY ; DESY, Zeuthen)
The last decades have seen tremendous progress in the experimental techniques for measuring key observables of the Standard Theory (ST) as well as in theoretical calculations that has led to highly precise predictions of these observables. Global electroweak fits of the ST compare the precision measurements of electroweak observables from lepton and hadron colliders at CERN and elsewhere with accurate theoretical predictions of the ST calculated at multi-loop level. [...]

Top Quark Mass
/ Mulders, Martijn (CERN)
Ever since the discovery of the top quark at the Tevatron collider in 1995 the measurement of its mass has been a high priority. As one of the fundamental parameters of the Standard Theory of particle physics, the precise value of the top quark mass together with other inputs provides a test for the self-consistency of the theory, and has consequences for the stability of the Higgs field that permeates the Universe. [...]

The W Boson Mass Measurement
/ Kotwal, Ashutosh V (Duke U.)
The measurement of the W boson mass has been growing in importance as its precision has improved, along with the precision of other electroweak observables and the top quark mass. Over the last decade, the measurement of the W boson mass has been led at hadron colliders. [...]

The Number of Neutrinos and the Z Line Shape
/ Blondel, Alain (Geneva U.)
The Standard Theory can fit any number of fermion families, as long as the number of leptons and quark families are the same. At the time of the conception of LEP, the number of such families was unknown, and it was feared that the Z resonance would be washed out by decaying into so many families of neutrinos! It took only a few weeks in the fall of 1989 to determine that the number is three. [...]
