The lattice part can be represented as lg={pg|tg}Tζg, which contains a point-group part pg ∈ O(3) and a translation vector tg. The spin rotation is decoupled from pg, under the constraint that {(φg∣∣lg)} f
Such a link can # be prevented in individual cases by putting a % sign in front of the word or # globally by setting AUTOLINK_SUPPORT to NO. # The default value is: YES.AUTOLINK_SUPPORT = YES# If you use STL classes (i.e. std::string, std::vector, etc.) but do not want #...
'by' may now be a character vector of column names. This allows syntax such as DT[,sum(x),by=key(DT)]. X[Y] now includes Y's non-join columns, as most users naturally expect, FR#746. Please do use j in one step (i.e. X[Y,j]) since that merges just the columns j uses...
the second term subtracts configurations where only one final-state particle is soft, while the remaining two particles form a hard-collinear pair: in this case, the soft emission factorises from the hard-collinear one, resulting in a single-radiative eikonal jet, so that fj must be a gluon...
