The growth of technology allowed for the design and construction of larger and more powerful particle accelerators, which physicists use to smash particles into each other and see what comes out. 0000049545 00000 n Tristy's the spry young sparkThat'll tread her and wed her and bed her and red herWithout ever winking the tail of a featherAnd that's how that chap's going to make his money and mark! The term "lepton" is introduced to describe objects that do not interact too strongly (electrons and muons are both leptons). By Andrew Zimmerman Jones, Daniel Robbins. Condon, Gamow, Gurney, alpha emission is due to quantum tunnelling, Hideki Yukawa combines relativity and quantum theory to describe nuclear interactions by an exchange of new particles (mesons called "pions") between protons and neutrons. 0000004164 00000 n 0000001615 00000 n James Joyce. The color sequence appears to be red-blue-green instead of red-green-blue for some odd reason. 0000024441 00000 n Mass of the top quark finally determined. 0000041507 00000 n 0000064807 00000 n 0000041926 00000 n 0000046731 00000 n Finnegans Wake. The top quark is more massive than many atoms and it is so unstable that is does not live long enough to combine with other quarks to form a hadron. The neutron is about the same size as the proton, so the pair of them is substantially larger than the electron. The particles were named the lambda0 and the K0. (1933–1934), Hideki Yukawa presents a theory of strong interactions and predicts mesons, Seth Neddermeyer, Carl Anderson, J.C. Street, and E.C. In 1963, when I assigned the name "quark" to the fundamental constituents of the nucleon, I had the sound first, without the spelling, which could have been "kwork." The color charge is the source of the name quantum chromodynamics, because “chroma” is Greek for “color.”. Nambu and and Han describe the SU(3) symmetry for quarks. �쥌5 K�C4+�>p&�1�7�3䡇���PB� � ku� endstream endobj 148 0 obj 607 endobj 92 0 obj << /Type /Page /Parent 78 0 R /Resources 93 0 R /Contents [ 105 0 R 107 0 R 109 0 R 116 0 R 120 0 R 127 0 R 134 0 R 136 0 R ] /MediaBox [ 0 0 648 756 ] /CropBox [ 0 0 648 756 ] /Rotate 0 >> endobj 93 0 obj << /ProcSet [ /PDF /Text ] /Font << /F5 114 0 R /F8 96 0 R /F11 94 0 R /F12 130 0 R /F15 99 0 R /F16 117 0 R /F17 123 0 R >> /ExtGState << /GS2 140 0 R >> /ColorSpace << /Cs6 103 0 R >> >> endobj 94 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 228 /Widths [ 278 296 389 556 556 833 815 204 333 333 500 606 278 333 278 278 556 556 556 556 556 556 556 556 556 556 278 278 606 606 606 444 737 722 722 722 778 722 667 778 833 407 556 778 667 944 815 778 667 778 722 630 667 815 722 981 704 704 611 333 606 333 606 500 333 556 556 444 574 500 333 537 611 315 296 593 315 889 611 500 574 556 444 463 389 611 537 778 537 537 481 333 606 333 606 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 204 389 389 0 556 1000 0 0 0 0 0 0 0 0 278 0 556 556 0 0 0 0 333 737 0 0 0 333 0 0 0 606 0 0 0 611 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 556 ] /Encoding /WinAnsiEncoding /BaseFont /DFIDDJ+NewCenturySchlbk-Roman /FontDescriptor 95 0 R >> endobj 95 0 obj << /Type /FontDescriptor /Ascent 737 /CapHeight 722 /Descent -205 /Flags 34 /FontBBox [ -195 -250 1000 965 ] /FontName /DFIDDJ+NewCenturySchlbk-Roman /ItalicAngle 0 /StemV 92 /XHeight 464 /CharSet (/G/three/x/u/N/quotedblright/H/I/E/v/four/quotedblleft/J/F/w/five/L/perc\ ent/d/y/emdash/six/M/b/z/seven/O/c/quoteright/eight/Q/e/parenleft/nine/R\ /f/colon/h/S/parenright/semicolon/i/U/endash/g/j/V/plus/k/equal/W/comma/\ K/m/l/hyphen/Y/o/question/period/Z/n/p/P/slash/q/T/dieresis/B/zero/r/spa\ ce/A/adieresis/C/one/s/exclam/D/a/two/t) /FontFile3 143 0 R >> endobj 96 0 obj << /Type /Font /Subtype /Type1 /FirstChar 1 /LastChar 75 /Widths [ 480 760 813 793 480 687 480 260 593 854 720 333 740 854 793 500 833 427 387 280 427 427 553 354 333 540 540 313 553 540 260 260 480 480 480 480 593 553 980 280 460 540 520 520 460 540 760 260 500 293 293 427 427 500 707 280 854 613 480 613 813 480 260 480 260 720 260 813 480 667 480 374 720 907 854 ] /Encoding 102 0 R /BaseFont /DFIDCL+TT1894O00 /FontDescriptor 98 0 R /ToUnicode 97 0 R >> endobj 97 0 obj << /Filter /FlateDecode /Length 655 >> stream H�b```f``�g`c`�Kgb@ !�;�E&��gw���q�������~���@ 0j��K�rT0��$�~^v��D�Eݜ�v�4�nYvı�$����R�V��22s�}yn��U%ᩔ�5�O�I���)����Δ� ���8�:u��1>R�$MtD���H�����Y޴�[��^��'&F������?f��!�C�� The first three quarks are proposed by Gell-Mann and Zweig (up, down, and strange). endstream endobj 98 0 obj << /Type /FontDescriptor /Ascent 766 /CapHeight 726 /Descent -253 /Flags 6 /FontBBox [ -47 -254 967 767 ] /FontName /DFIDCL+TT1894O00 /ItalicAngle 0 /StemV 0 /XHeight 426 /CharSet (/I/period/v/colon/h/P/Z/J/F/w/i/d/L/endash/semicolon/y/percent/zero/j/N/\ M/z/n/one/A/k/O/two/m/quoteright/x/Q/three/o/parenleft/R/K/p/quotedbllef\ t/S/parenright/four/T/q/five/U/g/B/copyright/space/r/b/six/C/plus/V/s/a/\ W/c/seven/D/comma/l/t/eight/e/G/hyphen/u/quotedblright/H/Y/nine/f) /FontFile3 101 0 R >> endobj 99 0 obj << /Type /Font /Subtype /Type1 /FirstChar 32 /LastChar 181 /Widths [ 287 296 333 574 574 833 852 241 389 389 500 606 278 333 278 278 574 574 574 574 574 574 574 574 574 574 278 278 606 606 606 500 747 759 778 778 833 759 722 833 870 444 648 815 722 981 833 833 759 833 815 667 722 833 759 981 722 722 667 389 606 389 606 500 333 611 648 556 667 574 389 611 685 370 352 667 352 963 685 611 667 648 519 500 426 685 611 889 611 611 537 389 606 389 606 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 287 574 574 287 287 287 287 287 747 287 287 287 287 287 287 287 606 287 287 287 685 ] /Encoding /WinAnsiEncoding /BaseFont /DFIDDH+NewCenturySchlbk-Bold /FontDescriptor 100 0 R >> endobj 100 0 obj << /Type /FontDescriptor /Ascent 737 /CapHeight 722 /Descent -205 /Flags 262178 /FontBBox [ -165 -250 1000 988 ] /FontName /DFIDDH+NewCenturySchlbk-Bold /ItalicAngle 0 /StemV 154 /XHeight 475 /CharSet (/period/F/seven/a/zero/nine/Q/three/four/E/five) /FontFile3 137 0 R >> endobj 101 0 obj << /Filter /FlateDecode /Length 16917 /Subtype /Type1C >> stream
