Description
We present the unpolaried parton distribution functions of $\Delta^+$ baryon in lattice simulation based on large momentum effective theory. We use $N_f=2+1+1$ twist mass fermion with colver term and pion mass is 260 MeV. The simulation is done using fixed sink sequential inversion method with Gaussian-momentum-smeared source while the largest baryon momentum is 1.2GeV .By comparing the $\bar{d}-\bar{u}$ content in the proton with $\Delta^+$ baryon,the role of chiral symmetry in generating the sea flaovr asymmetry is tested.
