“…1. We note that even though the factorized form of the cross section is derived for strictly R 1, it was found that the factorization is a very good approximation even for fat jets with a relatively large jet radius of R ∼ 0.7 and even above [60][61][62][63], as pointed out also in [24]. These observations imply that the power corrections of the form O(R 2 ) to the factorization theorem in Eq.…”

“…The jet mass distribution has been addressed several times in the literature from the theoretical side, where the efforts have focused mostly on exclusive jet configurations where additional constraints are imposed on the final state particles, see for example [21][22][23][24] and references therein. While it is advantageous in some situations to consider exclusive final state jets, it is important to note that the inclusive jet cross section can be measured with the highest statistics since all jets in a given transverse momentum and rapidity interval are taken into account without any further restrictions.…”

We study jet mass distributions measured in the single inclusive jet production in proton-proton collisions pp → jet+X at the LHC. We consider both standard ungroomed jets as well as soft drop groomed jets. Within the Soft Collinear Effective Theory (SCET), we establish QCD factorization theorems for both cases and we study their relation. The developed framework allows for the joint resummation of several classes of logarithmic corrections to all orders in the strong coupling constant. For the ungroomed case, we resum logarithms in the jet radius parameter and in the small jet mass. For the groomed case, we resum in addition the logarithms in the soft threshold parameter z cut which is introduced by the soft drop grooming algorithm. In this way, we are able to reliably determine the absolute normalization of the groomed jet mass distribution in proton-proton collisions. All logarithmic corrections are resummed to the next-to-leading logarithmic accuracy. We present numerical results and compare with the available data from the LHC. For both the groomed and ungroomed jet mass distributions we find very good agreement after including non-perturbative corrections.

“…In this paper all the calculations are carried out in the small R limit. In this case, the small-angle soft mode along the jet direction can be singled out as an independent degree of freedom [32,34,61,62]. Such soft radiation is sensitive to the jet direction and the jet boundary and will be referred to as the coft mode in the following discussions, cf.…”

We perform a precise calculation of the transverse momentum ( q T ) distribution of the boson+jet system in boson production events. The boson can be either a photon, W , Z or Higgs boson with mass m V , and q T is the sum of the transverse momenta of the boson and the leading jet with magnitude q T = | q T |. Using renormalization group techniques and soft-collinear effective theory, we resum logarithms log(Q/q T ) and log R at next-to-leading logarithmic accuracy including the non-global logarithms, where Q and R are respectively the hard scattering energy and the radius of the jet. Specifically, we investigate two scenarios of p J T m V or p J T m V in Z+jet events, and we examine the q T distributions with different jet radii and study the effect of non-global logarithms. In the end we compare our theoretical calculations with Monte Carlo simulations and data from the LHC.

Inclusive jet production in p-p and p ̅-p collisions shows many of the same kinematic systematics as observed in single particle inclusive production at much lower energies. In an earlier study (1974) a phenomenology, called radial scaling, was developed for the single particle inclusive cross sections that attempted to capture the essential underlying physics of point-like parton scattering and the fragmentation of partons into hadrons suppressed by the kinematic boundary. The phenomenology was successful in emphasizing the underlying systematics of the inclusive particle productions. Here we demonstrate that inclusive jet production at the LHC in high-energy p-p collisions and at the Tevatron in p ̅-p inelastic scattering show similar behavior. The ATLAS inclusive jet production plotted as a function of this scaling variable is studied for √s of 2.76, 7 and 13 TeV and is compared to p ̅-p inclusive jet production at 1.96 TeV measured at the CDF and D0 at the Tevatron and p-Pb inclusive jet production at the LHC ATLAS at √sNN = 5.02 TeV. Inclusive single particle production at FNAL fixed target and ISR energies are compared to inclusive J/ production at the LHC measured in ATLAS, CMS and LHCb. Striking common features of the data are discussed.
