34. Multi-jet merging in the parton branching method

Armando Bermudez Martinez (DESY)

25/11/2019, 16:40

Transverse Momentum Dependent parton distributions obtained from the Parton Branching method are combined with leading-order calculations of Drell-Yan production with up to three partons in the final state. A modified version of the MLM merging algorithm is applied in order to remove double counting from the different jet multiplicities. The merging is tested using the differential jet rate...

30. Matching NLO with Paton Branching TMD's on inclusive Z and bbbar production

Mr Luis Ignacio Estevez Banos (DESY)

25/11/2019, 17:10

We present NLO predictions from Powheg (POWHEG_BOX_V2) and MC@NLO merged with Parton Branching TMD's for inclusive Z and bbar production. We compare predictions for range of mass 60 < Mz < 120 and 60 < Mbbbar < 120 (around Z mass) in order to study soft gluon radiation and resummation from quarks and gluons.

11. Parton shower based on TMD parton distributions

Melanie Schmitz (DESY)

25/11/2019, 17:40

We present a parton shower based on Transverse Momentum Dependent (TMD)
parton distributions obtained with the Parton Branching method. We investigate
how well the TMD parton shower reproduces the TMD parton distributions.
Applications of the TMD parton shower to LHC processes will be presented.

40. TMD splitting functions in kT-factorization and prospects for using them in the evaluation of TMD distribution functions

Lissa Keersmaekers (University of Antwerp)

25/11/2019, 18:10

We present an overview of the calculation of transverse momentum dependent (TMD) real emission contributions to splitting functions within kT-factorization. We discuss their properties, such as the limits in which they reduce to well known kernels.

We present an implementation of the splitting functions in a Monte Carlo simulation, based on the Parton Branching method. Results of TMD...
