To jsou skutečně stavy procesu. Stavy procesů, které ps označuje, jsou:

D Uninterruptible sleep (usually IO)
R Running or runnable (on run queue)
S Interruptible sleep (waiting for an event to complete)
T Stopped, either by a job control signal or because it is being traced.
W paging (not valid since the 2.6.xx kernel)
X dead (should never be seen)
Z Defunct ("zombie") process, terminated but not reaped by its parent.

a další znaky jsou:

< high-priority (not Nice to other users)
N low-priority (Nice to other users)
L has pages locked into memory (for real-time and custom IO)
s is a session leader
l is multi-threaded (using CLONE_THREAD, like NPTL pthreads do)
+ is in the foreground process group 

To vše můžete také najít na manuálové stránce pro ps, konkrétně PROCESS STATE CODES sekce.
