MEZONHO

MEZONHO, yak nav zarrahoi elementarii noustuvorand az sinfi adronho (zarrahoi elementarie, ki dar tasiri mutaqobilai zur ishtirok mekunand). Nomi «Mezonho» (yun mesos — mobayni) az hamin barmeoyad, ki massai avvalin Mezonhoi kashfshuda — l-mezon va k-mezon — qimathoi mobaynii massai proton va elektronro doshta nd. Mezonhoe, ki avval s-mezonho nom girifta budand, mansubi Mezonho nestand va az sababi nimsini doshtanashon dar aksuttasiri zur ishtirok namekunand. Minbad bisyor Mezonhoi digar (ba nom rezonanshoi bozoni) kashf karda shu­dand, ki umri nihoyat kutoh dorand va dar ayni hol massai bazeashon az massai proton ziyod ast. Mezonho homiloni quvvahoi yadroi meboshand. Mezonho khususan hangomi barkhurdi adronhoi balandanergiya beshtar tavlid meyoband.

Mezonhoi neytral va zaryaddor (doroi zaryadi elektrii musbat yo manfi),

ajobatashon sifri (mas., ya-M;), gayrisifri (mas., Ar-M.) va g. mavjudand. Mezonhoi sinnashon izotropi (O,—, 1), muvofiqan singletho, dubletho va triplethoi izotrbanro tashkil medihand. Muvofiqi tasnifoti hozirazamoni zarrahoi elemenatari Mezonhoi khosiyatashon qarib monand (nisbat ba prosesshoe, ki bo tasiri mutaqobili zur ba amal meoyand) ba nom guruhi «supermultinletho»-ro tashkil medihand, ki az 8 to 10 zarra dorand.
