A new method to measure the top-quark mass in high energetic hadron collisions is presented. We use theoretical predictions calculated at next-to-leading order accuracy in quantum chromodynamics to study the (normalized) differential distribution of the $t\bar{t} + 1\mbox{-jet}$ cross section with respect to its invariant mass $\sqrt{s_{t\bar{t} j}}$. The sensitivity of the method to the top-quark mass together with the impact of various theoretical and experimental uncertainties has been… 

Top-quark mass measurements using jet rates at LHC

This work presents a new method to measure the top-quark mass in hadronic collisions(1). The method uses the sensitivity of the t ¯ + 1-jet production on the top-quark mass. In detail we study the R

Top-quark mass extraction from $t\bar{t}j +X$ events at the LHC: theory predictions

Past work has proven the possibility of extracting the top-quark mass, one of the fundamental parameters of the Standard Model, from the comparison of theory predictions and experimental measurements

Top quark mass studies with tt¯j$$ t\overline{t}j $$ at the LHC

A bstractA precise measurement of the top quark mass, a fundamental parameter of the Standard Model, is among the most important goals of top quark studies at the Large Hadron Collider. Apart from

Determination of the top quark mass from leptonic observables

Invariant-mass distribution of top-quark pairs and top-quark mass determination

We investigate the invariant-mass distribution of top-quark pairs near the $2m_t$ threshold, which has strong impact on the determination of the top-quark mass $m_t$. We show that higher-order

Uncertainties on the theoretical input for $t\bar{t}j$ experimental analyses at the LHC

The precise measurement of the top-quark mass constitutes one of the main goals of the LHC top-quark physics program. One possibility to extract this parameter uses the ρs distribution, which depends

Differential distributions for top-quark hadro-production with a running mass

We take a look at how the differential distributions for top-quark production are affected by changing to the running mass scheme. Specifically we consider the transverse momentum, rapidity and
