Higgsi Bosonist<\/h2>\n

13. detsembri CERNi seminaril esitlesid ATLAS ja CMS Higgsi bosoni otsingute praegust seisu. P\u00f5hiline j\u00e4reldus on, et Standardmudeli Higgsi boson, kui ta olemas on, peab olema massiga 116-130 GeV ATLASe ja 115-127 GeV CMSi andmetel.<\/p>\n

\"\"<\/a>S\u00fcndmus, kus paistab neli m\u00fc\u00fconit (punased j\u00e4ljed) prootonite p\u00f5rkest ATLASEs. Selline s\u00fcndmus on koosk\u00f5las kahe Z osakesega, mis lagunevad kumbki kaheks m\u00fc\u00fconiks. Sellised s\u00fcndmused tekivad Standardmudeli protsessides ilma Higgsi osakesteta. Nad on ka v\u00f5imalikuks j\u00e4ljeks Higgsi osakese tekkest, aga et \u00f6elda, kas tegu on Higgsi signaaliga peab anal\u00fc\u00fcsima palju s\u00fcndmusi koos.<\/p>\n

\nHiggsi boson: ajalugu algab t\u00e4na. V\u00f5ib-olla.<\/a> (teadus.err.ee)<\/p>\n

Kes on Higgs ja mis on Higgs?<\/h2>\n

\"\"<\/a>Peter Higgs on f\u00fc\u00fcsikateoreetik, Edinburgh’i \u00fclikooli professor emeritus, t\u00e4naseks 82 aastat vana. Teda teatakse h\u00e4sti kuuek\u00fcmnendate aastate t\u00f6\u00f6de j\u00e4rgi, kus ta pakkus v\u00e4lja s\u00fcmmeetria rikkumise elektron\u00f5rga j\u00f5u teoorias. See seletaks elementaarosakeste massi p\u00e4ritolu. Higgsi mehhanismi peetakse \u00fcldiselt Standardmudeli osaks ja Higgsi bosonit nimetatakse otsituimaks osakeseks kaasaegses f\u00fc\u00fcsikas.<\/p>\n

\n

Higgsi mehhanismi seletatakse CERNis nii:<\/p>\n

\"\"<\/a><\/p>\n

Kujutlege ruumi, kus f\u00fc\u00fcsikud omavahel rahulikult vestlevad, ruum oleks nagu t\u00e4idetud Higgsi v\u00e4ljaga.<\/p>\n

\"\"<\/a>
\nKui m\u00f5ni v\u00e4ga tuntud teadlane sisse astub, tekitab ta l\u00e4bi ruumi liikudes h\u00e4irituse, t\u00f5mmates igal sammul enda \u00fcmber austajaid.<\/p>\n

\"\"<\/a><\/p>\n

Tunglejad loovad liikujale takistuse, millega ta omandab massi samal moel nagu osake l\u00e4bides\u00a0 Higgsi v\u00e4lja.<\/p>\n

\"\"<\/a><\/p>\n

Kui ruumi l\u00e4bib kuuldus kellegi saabumisest<\/p>\n

\"\"<\/a><\/p>\n

tekitab see sarnaseid tunglejate gruppe, aga sel korral ilma kuulsuseta. Need grupid oleksid selle analoogia j\u00e4rgi Higgsi osakesed.<\/p>\n","protected":false},"excerpt":{"rendered":"
