The anatomy of electroweak symmetry breaking Tome II: The Higgs bosons in the Minimal Supersymmetric Model

Abstract

The second part of this review is devoted to the Higgs sector of the Minimal Supersymmetric Standard Model. The properties of the neutral and charged Higgs bosons of the extended Higgs sector are summarized and their decay modes and production mechanisms at hadron colliders and at future lepton colliders are discussed.

Top quark mass determination from the energy peaks of b-jets and B-hadrons at NLO QCD

“…The blue dotted line in Fig. 6 is the prediction corresponding to putting |η b | < 1.5 GeV in the selection (8). Thanks to the good accuracy in the experimental determination of eta b also in this case we find that the determination of the top quark mass is not affected by imperfect measurements of the jets.…”

“…6. The dashed line gives the prediction for p T,b > 25 GeV in (8). This choice of different cuts would give a prediction for the top quark mass which is shifted with respect to the central prediction by 2.5 GeV.…”

“…An example of effect of adding radiation in decay is displayed in Fig. 2, for μ F = μ R = m t = 171 GeV and selection cuts given in (8). In particular, the bottom panel shows the ratio of the differential energy spectrum from the process (2) at production and decay NLO to that from the process (5), which manifests well the softening of the spectrum due to NLO corrections to the decay of the top quark.…”

“…An example of the hardening of the spectrum caused by clustering effects is shown in Fig. 1 for μ F = μ R = m t = 171 GeV and selection cuts given in (8). The bottom panel of the figure demonstrates the ratio of the differential energy spectrum from the process (4) to that from the process (5), from which we clearly see a (slight) hardening effect in the low energy regime.…”

Higgs-boson masses and mixing matrices in the NMSSM: analysis of on-shell calculations

“…It can solve the hierarchy problem, provides a Dark Matter candidate and leads to a unification of the gauge couplings, thus paving the way to a Grand Unified Theory. The most frequently studied realizations of SUSY are the Minimal Supersymmetric Standard Model (MSSM) [2][3][4][5] and the Next-toMinimal Supersymmetric Standard Model (NMSSM) [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. In contrast to the SM, in the MSSM two Higgs doublets are required.…”
