Kywords: Dira Equaion, Zirbwgung, Univrsal Quanum Wav Equaion, Quarnion Quanum Mhanis. Inroduion In 98 Dira inrodud his rlaivisi wav quaion []. H had wand o find an quaion for h lron ha would b onsisn wih spial rlaiviy dsrib h known fin sruur frquny sprum of hydrogn. In hnial rms h quaion was Lornz-ovarian. I orrly dsribd h fin sruur of hydrogn. Whn Dira xamind h soluions o his quaion, h found ha, muh o his surpris, i also prdid h lron s spin is magni momn. Prhaps vn mor surprising, his quaion also suggsd a posiivly hargd paril wih h mass of h lron ould xis. Basd on his quaion, in 93 Dira prdid wha h alld h ani-lron (a posiron) onfirmd xprimnally in 93. In 933 h shard wih Shrodingr h Nobl Priz for physis for his work in quanum mhanis. In dvloping his quaion, Dira assumd ha h lron was a poin-lik paril wih an lri harg qual o h xprimnally masurd harg of h lron. Dira howvr did no ry o dvlop visualizabl physial modls as aids o piuring or undrsing his mahmaial rsuls. Thr ar svral rsuls of Dira s quaion whih wr problmaial, dspi h quaion s gnral suss. I was mniond ha Dira did no in his priod amp o mak a physial modl of h lron did no suppor suh amps. Howvr, many of h propris of h Dira lron, inluding hs problmaial propris, lnd hmslvs o a physial modling approah, whih may hlp rsolv som of hs problmaial propris. Th Zirbwgung is a horial rapid moion of lmnary parils, in pariular lrons, ha oby h Dira quaion. Th xisn of suh moion was firs proposd by Erwin Shrodingr in 93 as a rsul of his analysis of h wav pak soluions of h Dira quaion for rlaivisi lrons in fr spa, in whih an inrfrn bwn posiiv ngaiv nrgy sas produs wha appars o b a fluuaion (a h spd of ligh) of h posiion of an lron around h mdian, wih a irular frquny of m, or approximaly.6 Hz. This vry rapid moion of h lron mans w anno loaliz h lron xrmly wll givs ris o h Darwin rm. This moion nvr bn obsrvd for a fr lron, bu h bhavior of suh a paril has bn simulad wih a rappd ion, by puing i in an nvironmn suh ha h non-rlaivisi Shrodingr quaion for h ion has h sam mahmaial form as h Dira quaion (alhough h physial siuaion is diffrn) [,3]. Thus, if w masur h vloiy omponn in any dirion, w should ihr g plus or minus. This sms qui surprising, bu w should no ha a omponn of h vloiy opraor dos no ommu wih momnum, h Hamilonian, or vn h ohr omponns of h vloiy opraor. If h lron wr masslss, vloiy opraors would om- Copyrigh SiRs.
2 A. I. ARBAB 3 mu wih momnum. In mor spulaiv horis of parils, lrons ar aually hough o b masslss, ging an ffiv mass from inraions wih parils prsn in h vauum sa. Baru Brakn [4] analyzd Shrodingr s Zirbwgung rsuls proposd a spaial dsripion of h lron whr h Zirbwgung would produ h lron s spin as h orbial angular momnum of h lron s inrnal sysm, whil h lron s rs mass would b h lron s inrnal nrgy in is rs fram. Th sas of dfini momnum ar no ign-sas of vloiy for a massiv lron. Th vloiy ign-sas mix posiiv ngaiv nrgy sas qually. Thus, whil momnum is a onsan of h moion for a fr lron bhavs as i did in non-quanum Mhanis, h vloiy bhavs vry srangly in h Dira hory, vn for a fr lron. Whil Dira quaion is a firs-ordr diffrnial quaion in spa im, Klin-Gordon quaions is a sond-ordr in spa im. Th wo quaions ar invarian undr Lornz ransformaions. W would lik in his papr o wri Dira quaion as a sond - ordr diffrnial quaion in spa im mimiking h sard wav quaion. In doing so, w hav found nw spa im ransformaions undr whih Dira quaion rprsns a paril wih zro mass. Morovr, h ordinary Dira quaion is invarian undr hs ransformaions. Inrsingly, h invarian of Klin-Gordon quaion undr hs ransformaion yilds Dira quaion. Th nw Dira quaion has many inrsing onsquns. As in h d Brogli hory, h lron is dsribd by a wavpak whos group vloiy is qual o h spd of ligh in vauum. Th naur of his wav may xplain h Zirbwgung xhibid by h lron as found by Shrodinr.. Quarnioni Quanum Mhanis: Dira-Lik Equaion Considr a paril dsribd by h quarnion wavfunion i, ψ. This is quivaln o spinor rprsnaion of ordinary quanum mhanis whih w hav rnly dvlopd [5]. Th voluion of his quarnion wavfunion is dfind by h hr quaions [5] m ψ, () ψ m ψ, () ψ. (3) Equaions () - (3) yild h wo wav quaions ψ m ψ m ψ ψ, (4) m m. (5) Using h ransformaion m Equaions () () bom ψ ψ,. (7), (6) Employing Equaion (6), Equaions (4) (5) ar ransformd ino h wav quaions, ψ,. (8) Th physial maning of h vor ψ is sill no lar. Bu I argu ha i an b assoiad wih fundamnal parils (g., quarks) ha making up all hadrons, sin i has hr omponns. In his way may rprsn a salar paril (boson). Noi ha Equaions (4) (5) an b obaind from h nrgy quaion E p, whr E E im, E is h oal nrgy of h paril, using h familiar quanum mhanial opraor rplamns, viz., pˆ i ˆ E i. E p is an nrgy quaion for a masslss paril. Thus, i is inrsing ha a massiv paril an b ransformd ino a masslss paril using Equaion (6). Sin nrgy is a ral quaniy, his quaion is physially apabl if i dsribs a paril wih imaginary mass. In his as h nrgy quaions spli ino wo pars; on wih E E m h ohr wih nrgy E E m. Suh nrgis an dsrib h sa of a paril aniparil. A hypohial paril wih an imaginary mass moving a a spd highr han spd of ligh in vauum is known as ahyon [6]. Hn, our abov quaion an b usd o ra h moion of ahyons. This implis ha our quaions, Equaions (4) (5), an b applid o ahyons. Som siniss propos ha nurino an b a ahyoni frmion [7]. This is in favor of h xprimnal finding ha h squard mass of nuriono is ngaiv [8]. W know ha Chrnkov radiaion is mid from a paril moving in a mdium wih spd grar han spd of ligh in vauum. Whn h spd xds h spd of Copyrigh SiRs.
3 4 A. I. ARBAB ligh in vauum, h xra nrgy aquird by h paril is ransformd in radiaion. This an happnd momnarily for a paril kping is oal nrgy onsrvd. Thus, h xss nrgy (spd) is suh ha i ompnsa h dissipaions. 3. Ordinary Quanum Mhanis: Dira s Equaion Dira s quaion an b wrin in h form [] im. (9) whr, σ, σ σ ar h Pauli maris.

I is inrsing o s ha h invarian of Klin- Gordon quaion undr h ransformaions dfind by Equaions (3) (5) yilds Dira quaion. Morovr, Dira quaion, viz., Equaion (9), is also invarian undr h ransformaions in Equaions (3) (5). Sin is a four omponns spinor, w an wri i in rms of wo omponns doubls, viz.,. Subsiuing hs domposd spinors in Equaion (), on obains h wo quaions mi m, (7) mi m, (8) Equaions (7) (8) imply wo nrgy soluions, on wih E E m h ohr wih nrgy E E m. Equaion () an b obaind from Equaions (4) or (5) by rplaing m by im. Thrfor, Equaions (4) (5) an rprsn imaginary massiv bodis (ahyons). D Brogli hypohsis ha all miroparils xhibi a wav naur. This is possibl if w dsrib a paril by a wavpak. In his way h group vloiy of h wavpak will b h vloiy of h moving paril. Howvr, a singl wav an dsrib a paril. In Dira s hory h lron is found o mov wih spd of ligh owing o Einsin s rlaiviy i mus hav a zro mass. Hn, his moion is problmai in Dira s hory.

Similarly, for anilokwis roaion, viz., i r ir, Equaion (4) yilds h Dira ngaiv nrgy Copyrigh SiRs.

This implis ha his plan wav is a ollion of wo wavs of wo diffrn frqunis bu sam wavlngh. I is hus a wavpak. W may assum ha a paril is a ombinaion of wo sas: on moving wih momnum k in on dirions h ohr wih momnum k is h opposi dirion wih vloiy of ligh,. This may imply an inrnal irular moion rsuling from h wo sas. Hn, in h lron rs fram h oal momnum is zro. Dos his irular moion giv ris o h spin of h lron? Dos his imply ha h lron is no fundamnal onsiss of som subsruur? Dira s hory of h rlaivisi lron did no inlud a modl of h lron islf, assumd h lron was a poin-lik paril. Noi ha sring hory posulad ha h lrons quarks wihin an aom ar no -dimnsional objs, bu rahr 3-dimnsional osillaing lins (srings). Th hory advoas ha hs srings an vibra, hus giving h obsrvd parils hir harg, mass spin. Aording o Equaion () a paril is in a posiiv nrgy sa whn is wavlngh is grar han h h Compon wavlngh,, ( > ), in a m ngaiv nrgy sa (aniparil) whn is wavlngh is smallr han h Compon wavlngh ( < ). Howvr, a paril xising in h ngaiv nrgy sa (aniparil) having will b in a sa of rs (rappd). Thus, h paril is in ssn a suprposiion bwn is mar animar sas, hs wo onradiory sids of is prsonaliy should inrfr, sing h paril quivring (Zirbwgung). Howvr, his phnomnon has nvr bn obsrvd xprimnally baus h moion is oo small oo fas o d in ral quanum sysms. Th group vloiy of a (non)-rlaivisi paril is qual o is vloiy. Equaions (9) () implis ha h group vloiy of h wavpak is givn by v g,. (5) k This implis ha no h lron as a whol ha osillas bu is onsiuns ha having zro mass. Hn ral parils ahyons ar parils mov wih spd of ligh. Howvr, h phas vloiy of ah wav omprising h wav pak is lss han spd of ligh in vauum, as vidn from Equaions () (). Th group vloiy v g dos no nssarily rquir a paril o hav m, as vidn from Equaion (). I is a ransin propry of h paril whn sn in a diffrn im fram ( ). Hn, h Dira s vloiy dilmma is now rsolvd. 4.
