vibhajit atisamamiti

kann bhautiki mein, vibhajit atisamamiti maanak model seey parey bhautiki key liye ack prastaav haye.
itihas.
ise teen patron mein alag seey prastaavit kiya gayaa thaa. juuna 2003 mein james wells dwara pahale adhik mamuli roop mein uchch kshamata mein prakritikta key baare mein dhaarana koo halke seey shithil kiya gayaa. maee 2004 mein nima arkani-hammed aur sawas demopolos ney tark diyaa kii uchch kshetra mein prakritikta maanak model seey parey naee bhautiki kaa prastaav karane key liye ack sateek maargdarshak naheen hoe sakati haye aur tark diyaa kii supersimetry koo ack alag tareeke seey mahsoos kiya jaa sakata haye joe gaze yugman ekikaran koo sanrakshit kartaa haye aur isamen ack dark matter ummidwar hotaa haye. juuna 2004 mein gian giudis aur andrea romanino ney ack samanya drishtikon seey tark diyaa kii yadi koee gaze yugman ekikaran aur ack dark matter ummidwar chaahata haye, tou vaha vibhajan atisamamiti una kuchh siddhanton mein seey ack haye joe maujood hain.

vibhajit atisamamiti (maanak model kanon seey parey) mein nae prakaash (~ tii. ee. vee.) kann hain
vibhajit atisamamiti key liye lagrangian uchch oorjaa atisamamiti key astitva seey seemit haye. vibhajit supersimetry mein paanch yugman hainh uchch chaturthansh yugman aur uchch shreni, uchch shreni aur goggino key beach chaar yukawa yugman. yugman ack mapdand, sootra _ 1 dwara nirdhaarit kiye jaate hain, usa paimaane parr jahan atee-samamit scalar vighatit hotey hain. supersimetry breaking scale key neeche, yeye paanch yugman renormalisation samooh sameekaran key madhyam seey tii. vee. scale taka vikasit hotey hain. bhavishya key raikhik takraav mein, inn yugman koo 1 pratishat star parr maapa jaa sakata haye aur phir punarsameenikaran samooh uchch oorjaa taka vikasit huaa yeh dikhaane key liye kii siddhant atyadhik uchch paimaane parr atisamamit haye.
lambe samay taka jeevit rahey.
vibhajan atisamamiti kii ullekhaniya visheshta yeh haye kii gluno jivankal key saath ack ardh-sthir kann bunn jaataa haye joe 100 sekand taka lamba hoe sakata haye. ack gluno joe isase adhik samay taka jeevit rahata haye, bigg baing nucleosynthesis koo baadhit karega yaa cosmick gaama kiranon key ack atirikt srot key roop mein dekhaa gayaa hoga. gluno lambe samay taka jeevit rahata haye kyonki yeh kewal ack squark aur ack kwark mein kshay curr sakata haye aur kyonki squark itane bhaari hotey hain aur yeye kshay atyadhik dabaaye jaate hain. iss prakaar, praakritik ikaaiyon mein gluno key kshay darr kaa anuman lagbhag lagaaya jaa sakata haye, sootra 2 key roop mein, jahan sootra 3 gluno vishram dravyamaan haye aur sootra 4 squark vishram dravyamaan haye. 1 tave key crum key gluno dravyamaan key liye, oopar ullikhit brahmand sambandhi seema squark dravyamaan parr lagbhag sootra _ 5 gave kii oopari seema nirdhaarit karati haye.
gluno kaa sambhaavit roop seey lamba jivankal tevatron aur badey hadron takaraane vaale parr alag-alag takaraane vaale hastakshar kii or leey jaataa haye. inn kanon koo dekhane key teen tareeke hainh
laabh aur kamiyaan.
split supersimetry gaze yugman ekikaran kii anumati detee haye jaisa kii supersimetry karati haye, kyonki jinn kanon mein tii. vee. paimaane seey parey dravyamaan hotaa haye, way ekikaran mein koee pramukh bhoomika naheen nibhaate hain. yeye kann gurutvaakarshan hain-jinamen anya kanon key liye ack chhota yugman (gurutvaakarshan antahkriya key crum kaa) hotaa haye, aur maanak model fermian key liye scalar bhagidar-arthaat, squark aur sleepton. baad vaalaa sabhi gaze coupling key beeta-karyon koo ack saath sthanantarit kartaa haye, aur unake ekikaran koo prabhaavit naheen kartaa haye, kyonki bhavya ekikaran siddhant mein way kanon kii ack poori peedhi kii tarah ack poorna suu (5) gunak banaate hain.
split supersimetry bhee gravitino cosmological samasya koo hull karati haye, kyonki gravitino dravyamaan tii. vee. kii tulanaa mein bahut adhik haye.
proton kshay darr parr oopari seemaaen bhee santusht kii jaa sakati hain kyonki squark bhee bahut bhaari hotey hain.
doosari or, paaramparik supersimetry key vipareet, vibhajit supersimetry padanukram samasya koo hull naheen karati haye joe 1979 seey maanak model seey parey nae bhautiki key prastaavon key liye ack praathamik prerana rahee haye. ack prastaav yeh haye kii padanukram samasya koo maanav karanon seey thheek-tune maanate hue "hull" kiya jaataa haye.

vibhajit atisamamiti key prati kuchh uchch oorjaa bhautiki samudaay key praarambhik drishtikon koo atisamamiti naamak ack parody dwara sachitra kiya gayaa thaa. aksar jaba bhautiki mein ack naee dhaarana prastaavit kii jaati haye tou ghutane kii noke kaa virodh hotaa haye. jaba uchch kshetra mein swabhavikta koo shuru mein nae bhautiki key liye ack prerana key roop mein prastaavit kiya gayaa thaa, tou iss dhaarana koo gambhirta seey naheen liya gayaa thaa. supersymmetric maanak model key prastaavit honey key baad, sheldon glasho ney chutaki lete hue kahaa kii 'aadhe kann pahale hii khoje jaa chuke hain.'25 varshon key baad, samudaay mein prakritikta kii dhaarana itani gahari hoe gaee thee kii ack siddhant kaa prastaav karna joe praathamik prerana key roop mein prakritikta kaa upayog naheen kartaa thaa, uska upahaas kiya gayaa thaa. vibhajan supersimetry aisee bhavishyavaniyaan karati haye joe maanak model aur nyuntam supersymmetric maanak model donon seey alag hain aur uchch kshetra mein prakritikta kii antim prakriti bhavishya key takraav parr ummeed kii jaayegi.
prakritikta key kaee mool pratipaadak abb yeh naheen maanate hain kii yeh nae bhautiki parr ack vishesh baadha honey chaahiye. kenneth willson ney mool roop seey isaki vakaalat kii thee, lekin haal hii mein ise apane currier key dauran apani sabse badee galatiyon mein seey ack kahaa haye. steven weinberg ney brahmand sambandhi sthiraank mein prakritikta kii dhaarana koo shithil kiya aur 1987 mein isake liye ack paryavaraniya spashteekaran key liye tark diyaa. leonard suskind, jinhone shuru mein takniki rung kaa prastaav rakhaa thaa, ack paridrishya aur gair-prakritikta kii dhaarana key dridh samarthak hain. sawas demopolos, jinhone shuru mein supersymmetric maanak model kaa prastaav rakhaa thaa, ney split supersimetry kaa prastaav rakhaa.
