The Belle II Membership Management System (B2MMS) was announced and presented at the 28B2GM at KEK in October 2017. Since January 2018 it is the exclusive source for Belle II authors, mailing, and voting.
All users who want to work in the context of the Belle II collaboration must register to the Belle II Membership Management System (B2MMS)to become so-called Belle II users.
According to the by-laws the B2MMS provides different categories. Belle II users are:
- all official members of the Belle II collaboration usually physicists and PhD students (Belle II members)
- temporary users such as students (if not official members),
- technical staff,
- visitors who need access to the Belle II collaborative services of non-Belle II institutions (Please choose the inviting institute as home).
Becoming a Belle II user consists of two steps:
- The identity of the user must be proven (authentication).
- The permission to become a Belle II user must be given (authorization).
Users will obtain login credentials (account name / password) (not an email address) from the DESY registry to log in to the Belle II collaborative services (B2CS). This is not a KEK account!
If you are interested in using the DESY Analysis Facility (NAF) which provides computing and storage resources for inactive work as a complementary approach to the Grid, you have to apply for access by logging in with your DESY credentials here and clicking Apply to join the group for NAF 2.0. Your membership in Belle II is mandatory!
The approval workflow and the creation of the credentials takes one workday in CE(S)T. Finally, users will obtain login credentials (account name / password) (not an email address) from the DESY registry. The registry informs the user by email.
The DESY registry will use the names you have given as 'given middle family' and create email addresses such as given.middle.family_AT_belle2.org. Make up your mind if you really want the middle name.
Already a Belle II user?
If you have once been a Belle II user, your record will remain even if your membership expires. Please never ever register again. Status and attributes of your record can be changed at any time; even after expiration or with a new institution. See Instructions for Users (login required).
Already a DESY user?
Users who have an account from former work at DESY even outside Belle II (summer student, other group etc.), please register for Belle II and denote the account name in the account field. It will be reactivated/prepared.
The registration as 'Physicist - permanent/staff' requires the approval of the institutional board (IB) on the basis of a formal application otherwise the request will be not be processed. Make sure to hand this in via your IR in before-hand! Please check the Belle II contacts web.
Please check your membership record in the Belle II Membership Management System (B2MMS). See docu of the Belle II Membership Management System.
Note: Unique identification of authors is done via the so-called ORCID. Make sure it is registered as described in B2MMS ORCID .
Please never ever register AGAIN or TWICE. A new registration does not extend or reset anything!
If you are unsure whether you have already registered, try to access the B2MMS where you will be asked to log in. To reset a lost password see the FAQ. Note: The password must be renewed after 6 month. You will be informed by email well in advance. Resetting a lost or missed password takes a few days.
Account names (string up to 8 numbers/characters) can not be changed!
If still unsure contact us at .
If your institution has changed, review and change your record according to the Instructions for Users.
If you hold a DESY account from another project which is not enable for Belle II yet, register and denote your already existing account name.
Asian colleagues, please note the naming conventions:
- first name = given name
- last name = family name
- A capital letter first followed by small letters
- Example: Toru Iijima
The account name is a case insensitive string of 4-8 characters. It is NOT an email address. Please chose a decent account name and please remember the initial password which is created for you when filling the portal You will need it when your account is ready. Please denote the DESY Requirements for Account Names and Passwords.
The DESY registry will use the names you have given as 'given middle family' and create email addresses such as given.middle.family_AT_belle2.org. Make up your mind if you really want the middle name. The spaces will be transformed to dots!
Example: 'Nino de Angelo' will become 'nino.de.angelo_AT_belle2.org' whereas 'Nino deAngelo' (no middle name) will end up in 'nino.deangleo_AT_belle2.org'.
The creation of the credentials in the DESY registry will start after the IR has approved the request and will take a workday. Keep in mind: DESY is on CE(S)T. Users will be informed on success and will be asked to login with the initial password and to set a new password.
According to the DESY Requirements for Account Names and Passwords the password expires every 6 month; users will be informed early enough. Please don't ignore the notification. Consider to use a password safe!
Belle II Registration By Invitation
- If you were invited and have received an email with a temporary Username / Password which is valid ONLY for the Registration Portal. Firefox works best. Other browser might cause problems due to their security settings. After logging in with the TEMPORARY account/password in the invitation email you will see the page on your right.

Belle II Registration with a Grid User Certificate

Please remind the account_name and THIS NEW password! An email will be sent to the representative (IR) of the Belle II institution who must approve the request.
As soon as the registration request is approved by the IR, the user will be added to the B2MMS. The credentials will be created in the DESY registry within the next work day (CE(S)T.
