The following -macros, which are listed here by related groups, provide these -additional special symbols for use in equations: -\index{symbols!physics} -\bigskip -\itemize - \itm \CS{bra}\arg{text} and \CS{ket}\arg{text} produce the -notations $\bra{\hbox{\it text}}$ and $\ket{\hbox{\it text}}$ -respectively for quantum mechanical states. \CS{vev}\arg{text} -produces $\vev{\hbox{\it text}}$ for a VEV (\idx{Vacuum Expectation Value}). - - \itm \CS{del}, \CS{grad}, and \CS{square} produce the notations -$\del$, $\grad$, and $\square$ for various derivatives. (The first two -are just synonyms for \cs{partial} and \cs{nabla}.) - - \itm \CS{degrees} is the degrees symbol. For example, |90\degrees| -produces ``90\degrees''. You can use \CS{degree} as a synonym. These -work equally well in math or text mode. - - \itm \CS{frac}\arg{numerator}\arg{denominator} produces the fraction -|{|\<numerator> |\over| \<de\-nomi\-nator>|}|, while -\hskip 0pt plus 6pt\CS{smallfrac}\arg{numerator}\arg{denominator} -\hskip 0pt plus 6pt -produces the same fraction in the smaller -subscript style type. \CS{half} produces a $\half$ in a size appropriate -to its usage. - - \itm \CS{simle} and \CS{simge} make the symbols $\simle$ and -$\simge$ to indicate "less than about" and "greater than about," -respectively. Synonyms for these are \CS{ltsim} and \CS{gtsim}. - - \itm \CS{parenbar} puts a bar in parentheses above a character; -this is often used to indicate either a particle or its antiparticle. -\CS{nunubar} and \CS{ppbar} are special cases. Thus -\TeXexample -$$ n \parenbar{n} \qquad \nu \nunubar \qquad p \ppbar $$ -|endTeXexample -gives -$$ -n \parenbar{n} \qquad \nu \nunubar \qquad p \ppbar -$$ - -\goodbreak - - \itm \CS{subrightarrow}\arg{text} puts the text under a right -arrow of the appropriate length. Thus -\TeXexample -$$ f(x) \subrightarrow{x \to 0} f(0) $$ -|endTeXexample -gives -$$ -f(x) \subrightarrow{x \to 0} f(0) -$$ - - \itm \CS{buildchar}\arg{\#1}\arg{\#2}\arg{\#3} gives character |#1| with -|#2| above it and |#3| below it, allowing the construction of a variety -of special symbols. \CS{overcirc} is a special case of this which puts -a small circle above a character, as in $\overcirc R$. This is often -used in general relativity and related fields. - - \itm \CS{vbigl}\arg{delim}\arg{size} and -\CS{vbigr}\arg{delim}\arg{size} produce very (or variably) big -delimiters, generalizing the Plain \TeX\ macros \cs{bigl}, \cs{Bigr}, -etc. They produce, respectively, the left and right delimiters -\meta{delim} with height \meta{size}, which can be given in pt., cm., -in., or any other valid units. Any valid delimiter may be used, but you -must be careful if you use parentheses and automatic parenthesis sizing -is also in effect (\Sect{paren}), because these conflict. You must -either turn off automatic parenthesis sizing (with \cs{offparens}) or -use \cs{lparen} or \cs{rparen} in place of `|(|' and `|)|'. - -\itm \CS{Leftcases}\arg{size} and \CS{Rightcases}\arg{size} give left -and right braces of size \meta{size} smashed to zero height; these can -be used in place of the \cs{cases} of Plain \TeX\ when it is desired to -put an equation number on each line. For example, -\TeXexample -|smalltt$$\EQNalign{ -m_e &= ~.511~\MeV \EQN lep;a \cr -m_\mu &= ~105~\MeV - \quad \Rightcases{50pt} \quad {\rm Leptons} - \EQN lep;b \cr -m_\tau &= 1784~\MeV \EQN lep;c \cr} -$$ -|endTeXexample -gives\index{equations!alignment} -$$\EQNalign{ -m_e &= ~.511~\MeV \EQN lep;a \cr -m_\mu &= ~105~\MeV - \quad \Rightcases{50pt} \quad {\rm Leptons} - \EQN lep;b \cr -m_\tau &= 1784~\MeV \EQN lep;c \cr} -$$ -Note that |\Leftcases| and |\Rightcases| do not provide automatic -spacing, which must be adjusted by the user as in the previous example. -There seems to be no simple way to obtain automatic spacing and to -allow an equation number on each line. - - - \itm \CS{sterling} produces the British currency mark \sterling. - - \itm The astronomical symbols for the sun and the earth are -\CS{sun} and \CS{earth}. For example, |$M_\sun$| and |$M_\earth$| give -$M_\sun$ and $M_\earth$. You can also use them outside of math mode. - - - \itm \CS{dimensions}\arg{units}\arg{power} is used for dimensional -analysis. The units appear in square brackets, raised to the given -power. For example to produce \dimensions{mass}{-3} you would type -|\dimensions{mass}{-3}|. - - \itm \CS{slashchar}\arg{letter} puts a slash through a character, the -notation for the contraction of a vector with Dirac $\gamma$ matrices -in Feynman graphs. For example -\TeXexample -$$ {\cal L} = - \bar\psi[i\slashchar{\partial} - e\slashchar{A}-m]\psi $$ -|endTeXexample -gives -$$ -{\cal L} = - \bar\psi[i\slashchar{\partial} - e\slashchar{A}-m]\psi -\,. -$$ -The results produced by |\slashchar| are not as good as one would -like. You can do somewhat better by adjusting the kerning of the |/| -by hand for each character. For example, -\TeXexample -\def\Aslash{A\kern -0.47em/} -|endTeXexample -\def\Aslash{A\kern -0.47em/}% -produces ``$\Aslash$''. But note that the angle of the slash is still -not quite what one would like for a slashed ``$A$.'' To really get good -looking slashed characters someone will have to create a new slashed -character math font using MetaFont. Meanwhile you can get by with -|\slashchar| or define your own using kerning. - -\enditemize -\bigskip\pagecheck{0.2\vsize} - - Abbreviations for units are normally set in Roman type even when used -in formulas. Special function (e.g., sine, cosine and logarithm) or -operator names are also set in Roman type, and \TeXsis\ adds some new -names to go with the old standards. - -\itemize - \itm \CS{Tr} and \CS{tr} give ``$\Tr$'' and ``$\tr$'' respectively for the -trace of an operator or of a matrix. \CS{diag} is used to denote a -diagonal matrix, as in $\eta_{\mu\nu}=\diag(-1,1,1,1)$. - - \itm \CS{real} and \CS{imag} give the symbols $\real$ and $\imag$ -for the real and imaginary parts of an expression; the spacing is like -that for any other function or operator. - - \itm \CS{eV}, \CS{keV}, \CS{MeV}, \CS{GeV}, and \CS{TeV} give the -abbreviations for energy units $\eV$, $\keV$, $\MeV$, $\GeV$, and -$\TeV$ respectively. - - \itm \CS{mb}, \CS{mub}, \CS{nb}, \CS{pb}, and \CS{fb} give the -abbreviations for cross section units $\mb$, $\mub$, $\nb$, $\pb$, and -$\fb$ respectively, while \CS{cmsec} gives $\cmsec$, the standard units -for luminosity in colliding beam accelerators. - - \itm \CS{units}\arg{name} is a generic macro to print in Roman type -the name of any units not covered by the macros above. For example, -you can say \CS{units}|{furlongs}| and \CS{units}|{fortnights}| -if you are using that particular system of units. -\enditemize - - - - Note that all of the abbreviations for units above are defined -without any spacing; to produce -$$ -{\cal L} = 10^{33}\,\cmsec, \qquad p_\perp = 8.3\,\GeV -$$ -you should type -\TeXexample -$$ -{\cal L} = 10^{33}\,\cmsec, \qquad p_\perp = 8.3\,\GeV -$$ -|endTeXexample -with a |\,| to make a thin space between the number and the units. - - -%>>> EOF TXSsymb.doc <<< |
