It is experimentally and theoretically challenging to determine the exact number of exited nuclear states and their properties, since the short lifetime of these exited states leads to strongly overlapping resonances. Using a polarized beam, a polarized target or using the polarization of the recoil nucleon helps to measure single or double polarization observables, finding an unambiguous...

The excitation spectrum of the nucleon is an important testing ground for quantum chromodynamics in the regime where it cannot be treated perturbatively. During the last two decades much progress has been made on the theory side, e.g. lattice gauge methods, and in experiments, particularly using energy tagged photon beams at electron accelerators, which has now reached a state where not only...

Experimental observables of Λ-deuteron (Λd) elastic scattering are expected to provide unique and independent constraints on several poorly-known dynamical parameters of the hyperon-nucleon interaction, such as the ΛN spin-triplet scattering length and the ΛNN three-body force. Currently, there are no Λd experimental data. In this work, we present a feasibility study of Λd elastic scattering...

Neutrino scattering experiments rely on neutrino event generators such as GENIE. Theoretical models used by GENIE have high uncertainties, so we will compare events from e-GENIE, an electron event mode of GENIE, with experimental electron scattering data. The goal of this project is to measure the deuterium pion electro-production cross sections in CLAS12. We will compare these cross...

almost pure strange content. The SRC/CT experiment with GlueX detector
offers a good opportunity to study the its photo-production at 9 GeV, where
the data was limited previously. I will introduce the physics motivation,
experiment configurations and preliminary analysis results of this topic. -

Tetraquark states are classified using the $SU(6)_{sf}$ spin-flavor symmetry and Young tableau technique. Further, by using the extension of Gursey-Radicati mass formula, masses of tetraquark states are predicted upto good level of accuracy. Also, Decay channels and decay widths of tetraquark states are calculated and found to be in good agreement with the experimental and available theoretical data.
