PDG rule 11j: The nature of Dark Matter (DM) is not known, and therefore a definitive classificationis too early.
Candidates within specific scenarios are classified therein, such as 1000022 for the lightest neutralino. Generic fundamental states can be given temporary codes in the range 51 - 60, with 51, 52 and 53 reserved for spin 0, 1/2 and 1 ones (this could also be an axion state). Generic mediators of s-channel DM pair creation of annihilationcan be given codes 54 and 55 for spin 0 or 1 ones. Separate antiparticles, with negativecodes, may or may not exist. More elaborate new scenarios should be constructed with n= 5 and nr = 9. APID: Only the 51-60 range is considered DM. The antiparticles are assumed to be existing.

In addition, there is a need to identify ”Q-ball” and similar very exotic (multi-charged) particles which may have large, non-integer charge.
These particles are assigned the ad-hoc numbering +/-100XXXY0, where the charge is XXX.Y. or +/-200XXYY0, where the charge is XX/YY. The case of +/-200XXYY0 is legacy, see https://gitlab.cern.ch/atlas/athena/-/merge_requests/25862 Note that no other quantum numbers besides the charge are considered for these generic multi-charged particles (e.g. isSUSY() is false for them). Such a model was used in previous Run-1 (1301.5272,1504.04188) and Run-2 (1812.03673,2303.13613) ATLAS searches.

PDG rule 11h A black hole in models with extra dimensions has code 5000040.
Kaluza-Klein excitations in models with extra dimensions have n = 5 or n = 6, to distinguish excitations of left-or right-handed fermions or, in case of mixing, the lighter or heavier state (cf. 11d). The non zero nr digit gives the radial excitation number, in scenarios where the level spacing allows these to be distinguished. Should the model also contain supersymmetry, excited SUSY states would be denoted by a nn_r > 0, with n = 1 or 2 as usual. Should some colored states be long-lived enough that hadrons would form around them, the coding strategy of 11g applies, with the initial two nnr digits preserved in the combined code.

PDG rule 16 Nuclear codes are given as 10-digit numbers ±10LZZZAAAI.
For a (hyper)nucleus consisting of n_p protons, n_n neutrons and n_Λ Λ’s: A = n_p + n_n + n_Λ gives the total baryon number, Z = n_p gives the total charge, L = n_Λ gives the total number of strange quarks. I gives the isomer level, with I= 0 corresponding to the ground state and I > 0 to excitations, see [http://www.nndc.bnl.gov/amdc/web/nubase en.html], where states denoted m, n, p ,q translate to I= 1–4. As examples, the deuteron is 1000010020 and 235U is 1000922350. To avoid ambiguities, nuclear codes should not be applied to a single hadron, like p, n or Λ^0, where quark-contents-based codes already exist.

PDG rule 11g: Within several scenarios of new physics, it is possible to have colored particles sufficiently long-lived for color-singlet hadronic states to form around them.
In the context of supersymmetric scenarios, these states are called R-hadrons, since they carry odd R- parity. R-hadron codes, defined here, should be viewed as templates for corresponding codes also in other scenarios, for any long-lived particle that is either an unflavored color octet or a flavored color triplet. The R-hadron code is obtained by combining the SUSY particle code with a code for the light degrees of freedom, with as many intermediate zeros removed from the former as required to make place for the latter at the end. (To exemplify, a sparticle n00000n˜q combined with quarks q1 and q2 obtains code n00n˜qnq1 nq2 nJ .) Specifically, the new-particle spin decouples in the limit of large masses, so that the final nJ digit is defined by the spin state of the light-quark system alone. An appropriate number of nq digits is used to define the ordinary-quark content. As usual, 9 rather than 21 is used to denote a gluon/gluino in composite states. The sign of the hadron agrees with that of the constituent new particle (a color triplet) where there is a distinct new antiparticle, and else is defined as for normal hadrons. Particle names are R with the flavor content as lower index. APID: Definition of R-Glueballs: 100099X (X=1,3), 100999Y (Y=1,5) APID: NB In the current numbering scheme, some states with 2 gluinos + gluon or 2 gluons + gluino could have degenerate PDG_IDs.

PDG rule 11d Fundamental supersymmetric particles are identified by adding a nonzero n to the particle number.
The superpartner of a boson or a left-handed fermion has n = 1 while the superpartner of a right-handed fermion has n = 2. When mixing occurs, such as between the winos and charged Higgsinos to give charginos, or between left and right sfermions, the lighter physical state is given the smaller basis state number.
