abstract = {The almost hermetic coverage of the CMS detector is used to
measure the distribution of transverse energy,
$E_\mathrm{T}$, over 13.2 units of pseudorapidity, $η$, for
pPb collisions at a center-of-mass energy per nucleon pair
of $\sqrt{s_\mathrm{NN}}=$ 5.02 TeV. The huge angular
acceptance exploits the fact that the CASTOR calorimeter at
$-6.6<η<-5.2$ is effectively present on both sides of the
colliding system because of a switch in the proton-going and
lead-going beam directions. This wide acceptance enables the
study of correlations between well-separated angular regions
and makes the measurement a particularly powerful test of
event generators. For minimum bias pPb collisions the
maximum value of d$E_\mathrm{T}/$d$η$ is 22 GeV, which
implies an $E_\mathrm{T}$ per participant nucleon pair
comparable to that of peripheral PbPb collisions at
$\sqrt{s_\mathrm{NN}}=$ 2.76 TeV. The increase of
d$E_\mathrm{T}/$d$η$ with centrality is much stronger for
the lead-going side than for the proton-going side. The $η$
dependence of d$E_\mathrm{T}/$d$η$ is sensitive to the $η$
range in which the centrality variable is defined. Several
modern generators are compared to these results but none is
able to capture all aspects of the $η$ and centrality
dependence of the data and the correlations observed between
different $η$ regions.},
