Boson Higgs adalah satu-satunya partikel dasar prediksi Model Standar yang belum diamati dalam [[eksperimen fisika partikel]].<ref name="Griff">{{cite book|last = Griffiths|first = David|authorlink = David Griffiths (physicist)|title = Introduction to Elementary Particles|url = https://archive.org/details/introductiontoel00grif_752|edition = Second, Revised|year = 2008|publisher = [[Wiley-VCH]]|isbn = 978-3-527-40601-2|page = [https://archive.org/details/introductiontoel00grif_752/page/n417 403]|chapter = 12.1 The Higgs Boson|quote = The Higgs particle is the only element in the Standard Model for which there is as yet no compelling experimental evidence.}}</ref> Partikel ini adalah bagian integral dari [[mekanisme Higgs]], bagian dari Model Standar yang menjelaskan bagaimana sebagian besar partikel dasar yang telah diketahui memperoleh [[massa]]nya.<ref group="Note">Massa partikel komposit seperti proton dan neuron hanya ada karena mekanisme Higgs, dan sudah diakui sebagai akibat dari [[interaksi kuat]].</ref> Misalnya, mekanisme Higgs akan menjelaskan mengapa [[boson W dan Z]], yang menjadi perantara interaksi lemah, memiliki massa sementara [[foton]], yang menjadi perantara elektromagnetisme, tidak memiliki massa. Boson Higgs diperkirakan termasuk dalam kelas partikel [[boson skalar]] ([[boson]] adalah partikel dengan [[putaran (fisika)|putaran]] integer, dan boson skalar memiliki putaran 0.) <!--The photon is a kind of boson and so is the less-familiar [[gluon]], along with the W and Z particles mentioned above. These particles are all [[vector boson]]s, with spin 1. At present there are no known elementary scalar bosons in nature, although many composite spin-0 particles are known.-- --Is all this relevant?-->
Teori yang tidak membutuhkan boson Higgs juga muncul dan akan dipertimbangkan jika keberadaan boson Higgs ditiadakan. Teori-teori tersebut disebut sebagai [[model nir-Higgs]]. Sejumlah teori menyatakan bahwa mekanisme apapun yang mampu menciptakan massa partikel dasar harus tampak dengan energi kurang dari 1,4 [[TeV]];<ref>{{cite journal

Pada akhir 2011 sejumlah percobaan berangsur-angsur telah menekankan kisaran massa sekitar {{val|125|ul=GeV/c2}}. Pada tanggal 4 Juli 2012, tim eksperimen [[Compact Muon Solenoid|CMS]] dan [[Percobaan ATLAS|ATLAS]] pada Large Hadron Collider secara independen mengumumkan bahwa mereka mengkonfirmasi penemuan boson yang belum diketahui sebelumnya dengan massa antara 125-127 GeV/c<sup>2</sup>, yang
