The Higgs boson turns ten

The profile of the Higgs boson: status and prospects

“…The first handbook focussed on inclusive observables [11], the second one addressed differential distributions [12], the third delved into Higgs boson properties [13], and the fourth specifically aimed to decipher the nature of the Higgs sector [14]. Since 2016, the field has witnessed significant advancements, and this review primarily highlights the progress made during this period (see also [15,16]). A significant part of the theoretical advancements concerns the computation of higher-order total cross sections.…”

N3LO+N3LL QCD improved Higgs pair cross sections

“…[73]. 6 The finite top quark mass corrections can be included either by taking into account more terms in the [43,[75][76][77][78][79] or by rescaling m t → ∞ amplitudes (cross sections) with the known full-m t dependent amplitudes (cross sections) [52,[80][81][82]. Moreover, there are also many interesting attempts to compute the two-loop ggF di-Higgs amplitudes in the analytic forms by taking various approximations [83][84][85][86][87].…”

“…The shape of the Higgs potential has in fact the far reaching influences on cosmology (see e.g., refs. [5,6]). The distinct fates of our universe are determined by the vacuum stability…”

“…It is also alternatively called the "heavy top quark mass approximation" or "large top quark mass approximation" or dubbed as the Higgs effective field theory (HEFT) approach in the literature 6. An earlier threshold resummation at a lower accuracy was carried out in ref [74]…”

Particle physics isn’t going to die — even if the LHC finds no new particles

“…To complete the picture, researchers also need to probe the interactions between the Higgs boson and lighter particles -those, such as electrons, that form the building blocks of everyday matter. As Giulia Zanderighi at the Max Planck Institute for Physics in Munich, Germany, and her colleagues discuss in a Perspective on page 41, the LHC should be able to take scientists some way towards this aim, but a new generation of colliders will probably be needed to get the job done 5 . How best to investigate these interactions at the LHC, and the question of what other experiments might be needed, are active areas of research.…”
