Author listing on Belle II papers

Dear Belle II colleagues,

As mentioned at the B2GM closeout session, it's necessary for you to confirm how you want your name to be listed on Belle II preprints and publications. The procedure for doing this is simple, takes < 5 minutes, and needs to be done only once (assuming your preference doesn't change). The steps are as follows, along with examples of how to list various names.

1) Log in to B2MMS at b2mms.belle2.org with your DESY credentials.
2) Click on “Show my record” in the upper left corner of the page.
3) Click on the magnifying glass icon at the left end of your record.
4) Click on the “Edit Values” checkbox at the top of the page.
5) Edit the default entry in the “Name in LaTeX” box according to your preference. (See rules below.)
6) Click on the “Update Data” button at the top right corner of the page.

Rules for the “Name in LaTeX” entry:

An author named Penelope Maria de la Garza might use P.~de~la~Garza [no middle initial]
  x  not Penelope~de~la~Garza [abbreviate first name]
  x  not P. de la Garza [use non-breaking space - the tilde - for each space to avoid a line break in the middle of your name]
  x  not P.~de~la~garza [capitalize first letter of surname]
  x  not P.~de~la~GARZA [do not capitalize entire surname]
  x  not P.~De~La~Garza [do not capitalize a nobility particle unless it is joined with the surname, e.g., DuPont]

An author named Aloysius Luigi Gonzaga might use A.~L.~Gonzaga [with middle initial]
An author named Hee-Young Park might use H.-Y.~Park [dash instead of tilde between first and middle initial]
For accented letters, use \v{c} or \'{e} or \`{a} or \"{u} or \c{c} etc.

best regards,

Leo Piilonen (L.~E.~Piilonen)                 Alan Schwartz (A.~J.~Schwartz)
