Top 5 Implications of Finding the Higgs Boson The Higgs boson has long been thought the key to resolving the mystery of the origin of mass. If physicists confirm that the Higgs boson exists, the discovery would also confirm that the Higgs mechanism for particles to acquire mass is correct. And, it may offer clues to the next mystery down the line, which is why individual particles have the masses that they do. The Standard Model is the reigning theory of particle physics that describes the universe’s very small constituents. Every particle predicted by the Standard Model has been discovered — except one: the Higgs boson. Discovering the Higgs boson would also help explain how two of the fundamental forces of the universe — the electromagnetic force that governs interactions between charged particles, and the weak force that’s responsible for radioactive decay — can be unified. Another theory that would be affected by the discovery of the Higgs is called supersymmetry. This idea posits that every known particle has a “superpartner” particle with slightly different characteristics. The Large Hadron Collider is the world’s largest particle accelerator. It was built for around $10 billion by the European Organization for Nuclear Research (CERN) to probe higher energies than had ever been reached on Earth. Finding the Higgs boson was touted as one of the machine’s biggest goals. ShortURL

Pronađena Božja čestica? Svjetska znanstvena zajednica bruji nakon anonimnog komentara na blogu matematičara Petera Woita Dok se jedan dio znanstvenika kune da je anonimni post zezancija, dobar dio njih uvjeren je da tu ima nečega i da je moguće da je LHC napokon ispunio ono zbog čega je i napravljen - snimio Higgsov bozon, prozvan i Božjom česticom. Higgsov bozon do sada nije „pronađen", postoji samo ideja da bi trebao postojati prema teoriji fizike čestica poznatoj kao Standardni model. Bozon bi trebao prenositi masu na ostale čestice i prema Standardnom modelu bio je, na neki način, stvoritelj svemira nakon Velikog praska. Fizičari vjeruju da pronalazak Higgsovog bozona može objasniti zašto objekti zapravo imaju masu. LHC i Tevatron u Fermilabu traže dokaze postojanja Higgsovog bozona, no do sada nije bilo uspjeha u potrazi za Božjom česticom koja se odvija sudaranjem čestica velikom brzinom. Prema anonimnom postu, u zadnjem je pokusu u LHC-u došlo do bilježenja signala koji je masom i ostalim karakteristikama jednak predviđanjima Higgsa. No, neki od aspekata signala ne odgovaraju predviđanjima, pa je tako brzina njegovog stvaranja puno veća od očekivane, što bi s druge strane moglo značiti da je pronađena čestica o kojoj ne postoje niti teorije.
