হিগস বোসন
One possible signature of a Higgs boson from a simulated proton–proton collision. It decays almost immediately into two jets of hadrons and two electrons, visible as lines.[Note ১] |

হিগস বোসন বা হিগস কণা, কিংবা ভুলভাবে ঈশ্বর কণা (ইংরেজি ভাষায়: Higgs boson বা Higgs particle; God Particle) পদার্থবিজ্ঞানের স্ট্যান্ডার্ড মডেলের প্রস্তাবিত প্রাথমিক কণা। হিগস ক্ষেত্র এবং তার সহযোগী হিগস বোসন অস্তিত্ব সহজ কয়েকটি পদ্ধতির মাধ্যমে[৪] কিভাবে কিছু প্রাথমিক কণা ভর আছে ব্যাখ্যা করা হবে।স্ট্যান্ডার্ড মডেল বলছে এই কণার হিগস ক্ষেত্র, যা অ শূন্য শক্তি আছে সর্বত্র এমনকি অন্যথায় ফাঁকা জায়গাও, সাথে আলাপচারিতার দ্বারা ভর অর্জন।
