Nucleon spin and quark content at the physical point
C. Alexandrou, M. Constantinou, K. Hadjiyiannakou +5
We present results on the spin and quark content of the nucleon using twisted mass clover-improved fermion simulations with a pion mass close to its physical value. We use…
Gluon momentum fraction of the nucleon from lattice QCD
Constantia Alexandrou, Martha Constantinou, Kyriakos Hadjiyiannakou +3
We perform a direct calculation of the gluon momentum fraction of the nucleon using maximally twisted mass fermion ensembles with flavors at a pion mass of about $370\,…
Updated Lattice Results for Parton Distributions
Constantia Alexandrou, Krzysztof Cichy, Martha Constantinou +4
We provide an analysis of the x-dependence of the bare unpolarized, helicity and transversity iso-vector parton distribution functions (PDFs) from lattice calculations employing (m…
Recent results for the proton spin decomposition from lattice QCD
Constantia Alexandrou, Martha Constantinou, Kyriakos Hadjiyiannakou +7
The exact decomposition of the proton spin has been a much debated topic, on the experimental as well as the theoretical side. In this talk we would like to report on recent non-pe…
A Lattice Calculation of Parton Distributions
Constantia Alexandrou, Krzysztof Cichy, Kyriakos Hadjiyiannakou +3
We present results for the dependence of the unpolarized, helicity, and transversity isovector quark distributions in the proton using lattice QCD, employing the method of quas…
