Een beetje grieks en wiskunde in LaTeX mode:

A further analysis focuses on an exclusive $b$-decay mode, namely $B_{d}\rightarrow J/\psi K_{S}^{0}$, which is one of a number of decays that are interesting for studies of CP violation in the B system.

Bij Alice doen ze dit:

${\frac {{\rm {d}}^{3}N}{{\rm {d}}p_{t}^{2}{\rm {d}}\phi {\rm {d}}y}}={\frac {{\rm {d}}^{2}N}{2\pi {\rm {d}}p_{t}^{2}{\rm {d}}y}}[1+2\sum _{n}{v_{n}{\rm {cos}}(n(\phi -\Psi _{R}))}]$

In the Standard Model,$B_{d}^{0}-{\overline {B_{d}^{0}}}$ mixing is a direct consequence of second order weak interactions. Starting with a $B_{d}^{0}$ meson produced at time $t$=0, the probability, ${\mathcal {P}}$, to observe a ${\overline {B_{d}^{0}}}$ decaying at the proper time $t$ can be written, neglecting effects from ${\mathcal {CP}}$ violation: ${\mathcal {P}}(B_{d}^{0}\rightarrow {\overline {B_{d}^{0}}})~=~{\frac {\Gamma _{d}}{2}}e^{-\Gamma _{d}t}[\cosh({\frac {\Delta \Gamma _{d}}{2}}t)~+~\cos(\Delta m_{d}t)]$. Here $\Gamma _{d}~=~{\frac {\Gamma _{d}^{H}~+~\Gamma _{d}^{L}}{2}}$, Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \Delta \Gamma_d~=~\Gamma_d^H -\Gamma_d^L} , and Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle \Delta m_d~=~m^H_d~-~m^L_d} , where $H$ and Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle L} denote respectively the heavy and light physical states.

Kijk eens bij Preferences, daar kun je instellen hoe de Math-mode weergegeven kan worden. Ik (Kees) heb het nu staan op "HTML if simple, else PNG". De math statements hierboven worden in-line html weergegeven, behalve de ingewikkelde Alice vergelijking. Als je het als 'always PNG' insteld wordt het mooier, maar dan zijn alle in-lines groter dan de tekst.

Ik merk net dat alle tijdsaanduidingen in GMT zijn en niet in nederlandse zomertijd... dit kun je in je Setting aanpassen bij 'time zone'; zet hier 02:00 in het vakje.
