v8 v9 14 14 The particle spectra of 2UED includes all of the Standard Model particles as well as their Kaluza-Klein excitations in either one or both of the compactified extra dimensions. Upon compactification one recovers the four dimensional gauge fields, but are left with 2 extra components. One of these components, the spinless adjoint to the gauge field, is invariant under 6D gauge transformations. The other, orthogonal excitation, shifts under such a transformation and corresponds to the Nambu-Goldstone boson eaten by the massive vector gauge field level by level. The 6D fermions have four components corresponding to the + or - 6D chiralities and the familiar L and R 4D chiralities. In order to insure 6D anomaly cancellation and fermion mass generation, the chiralities of the weak-doublet quarks (leptons) are forced to be opposite those of the weak-singlet quarks (leptons). That is, for each generation of quarks, there are the following fields: Q+ = (U+,D+), U-, D-, as well as the analogous fields for the leptons. Each of these 6D chiralities is composed of a combination of L and R handed components. Below is a table summarizing the 2UED particle content for the (0,0), (1,0) and (1,1) levels of excitation, where (0,0) are the standard model fields, (1,0) are fields with excitations in 1 extra dimension and (1,1) are fields with excitations in both extra dimensions. 15 15 16 16 ||''' ''Standard Model Fields'' '''|||||||||||| 17 17 ||'''Particle Name'''||'''Mode'''||'''Description'''||'''FeynRules Name'''||'''MG Name'''||'''CH Name'''|| 18 ||u||(0,0)||Standard Model up quark||u ||u 18 ||u||(0,0)||Standard Model up quark||u ||u|| || 19 19 ||d||(0,0)||Standard Model down quark||d ||d || || 20 20 ||c||(0,0)||Standard Model charm quark||c||c || || … … 24 24 ||e||(0,0)||Standard Model electron||e||e || || 25 25 ||ve||(0,0)||Standard Model electron neutrino||ve||ve || || 26 ||mu||(0,0)||Standard Model muon||m|| 26 ||mu||(0,0)||Standard Model muon||m||m|| || 27 27 ||vmu||(0,0)||Standard Model muon neutrino||vm||vm || || 28 ||tau||(0,0)||Standard Model tau ||tt|| 28 ||tau||(0,0)||Standard Model tau ||tt||tt|| || 29 29 ||vtau||(0,0)||Standard Model tau neutrino||vt||vt || || 30 30 ||A||(0,0)||Standard Model photon ||A||a || || … … 32 32 ||W||(0,0)||Standard Model W-boson ||W||w || || 33 33 ||g||(0,0)||Standard Model gluon ||G||g || || 34 35 ||''' ''(1,0) Fields'' '''|||||||||||| 36 ||'''Particle Name'''||'''Mode'''||'''Description'''||'''FeynRules Name'''||'''MG Name'''||'''CH Name'''|| 37 ||E10+||(1,0)||chirality + electron||e10L||e10l-|||| 38 ||VE10+||(1,0)||chirality + electron-neutrino||e10L||e10l-|||| 39 ||Mu10+||(1,0)||chirality + muon||m10L||m10l-|||| 40 ||VMu10+||(1,0)||chirality + muon-neutrino||m10L||m10l-|||| 41 ||Tau10+||(1,0)||chirality + tau||t10L||t10l-|||| 42 ||VTau10+||(1,0)||chirality + tau-neutrino||t10L||t10l-|||| 43 44 34 45 35 46
