Abstract
We study the factorization and resummation prediction on the jet mass spectrum in onejet inclusive production at the LHC based on softcollinear effective theory The soft function with antik T algorithm is calculated at nexttoleading order and its validity is demonstrated by checking the agreement between the expanded leading singular terms with the exact fixedorder result The large logarithms ln n m J 2 /p T 2 and the global logarithms ln n s4/p T 2 in the process are resummed to all order at nexttoleading logarithmic and nexttonexttoleading logarithmic level respectively The cross section is enhanced by about 23 from the nexttoleading logarithmic level to nexttonextto leading logarithmic level Comparing our resummation predictions with those from Monte Carlo tool PYTHIA and ATLAS data at the 7 TeV LHC we find that the peak positions of the jet mass spectra agree with those from PYTHIA at parton level and the predictions of the jet mass spectra with nonperturbative effects are in coincidence with the ATLAS data We also show the predictions at the future 13 TeV LHCThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
