Are there really any experimental limits on a light higgs boson?

Summary

The experimental evidence regarding a light Higgs boson is reviewed. It is shown that a light Higgs boson with almost any mass between 14 MeV/c2 and 1 GeV/c2 is still allowed by existing data. The only limit in this range comes from B decay data which, for sufficiently large values of the top quark mass, exclude a Higgs boson with a mass between 2mμ and 700 MeV/c2. Discussions of light Higgs boson emission in the decays of K, π, μ, τ, η′, and γ are also given.

Сушествуют ли реально зкспериментальные пределы для легкого боэона Хиггса?

Реэюме

Исследуются зкспериментальные докаэательства, касаюшиеся легкого боэона Хиггса. Покаэывается, что, согласно сушествуюшим зкспериментальным данным, допускается легкий боэон Хиггса с проиэвольной массой в интервале от 14 MзB/c2 до 1 ГзB/c2. Единственное ограничение в зтой области воэникает иэ данных для В распада, которые для достаточно больщих эначений массы верхнего кварка исключают боэон Хиггса с массой между 2mμ и 700MзB/c2. Также обсуждается испускание легкого боэона Хиггса в распадах К, π, μ, τ, η′ и γ.

Riassunto

Si esaminano le prove sperimentali che riguardano il bosone leggero di Higgs. Si mostra che un bosone leggero di Higgs con una massa qualunque compresa tra 14 MeV/c2 e 1 GeV/c2 è ancora ammesso dai dati attuali. L’unico limite in questo intervallo deriva dai dati nel decadimento di B che, per valori sufficientemente grandi della massa del quark top, escludono un bosone di Higgs con massa compresa tra 2mμ e∼700 MeV/c2. Si discute anche l’emissione di un bosone di Higgs leggero nei decadimenti di K, π, μ, τ, η′ e γ.

    The paper byP. Avery et al. (ref. (23)) presented a limit ofB 3 ⩽ 0.0031 but implies that experimental cuts make this number inapplicable when the muon pair results from the decay of a light Higgs boson. The limit quoted is explicitly given in their paper for the case of light Higgs boson emission and decay.CrossRefGoogle Scholar
