“…Among these measurements, the decay Λ + c → pπ + π − is observed for the first time, and the precision of the branching fraction for Λ + c → pK + K − non-φ and Λ + c → pφ is significantly improved. Hadronic decays of charmed baryons provide an ideal laboratory to understand the interplay of weak and strong interaction in the charm region [1][2][3][4][5][6][7][8][9], which is complementary to charmed mesons. They also provide essential input for studying the decays of b-flavored hadrons involving a Λ c in the final state [10,11].…”

“…The polarization of the Λ + c baryons has been measured in the reaction of 230 GeV/c protons with a Copper target and gives P(Λ + c ) = −0.65 [44] (the sign of the polarization is defined with respect to the normal to the production plane, q × p i ). The E791 experiment [45] finds evidence for an increasingly negative polarization of Λ + c as a function of p 2 t , in agreement with the model [46][47][48].…”

“…By convolving the transverse momentum distribution and polarization curve as a function of transverse momentum we obtain the mean square value of Λ + c polarization around -0.37 and −0.40 ± 0.05 for the theoretical prediction and experimental data, respectively. Experimental data: red crosses [45], orange rectangular area [44]; dashed red curves -experimental data fit by the normal distribution; solid red curve -theoretical prediction by the so-called hybrid model [48] for the process…”

“…The baryon spin-1/2 and spin-3/2 multiplets are discussed in detail in the previous section and [15,38] which puts the quark model approach to non-leptonic charm baryon decays on a much sound theoretical footings. Some of the theoretical predictions relative this thesis are listed in Table 2.2.…”

This dissertation reports on a study of the relative branching fraction measurement of the charmed baryon Λ c decaying to the Cabibbo-suppressed modes.A data sample of 125 fb −1 is used for these measurements. This data samples ii experiments and also to the theoretical predictions (wherever needed) are also given.iii To my father and (late)mother iv AcknowledgmentsAs with any major endeavour, this thesis was not created in vauum but rather in a fertile academic enviornment with the assistance of many people. I cannot hope to mention every person who has played a part but some individuals are worthy of specific mention. I am highly indebted to Dr. Prafulla K. Behera of University of Pennsylvania, who took upon himself "to show me the ropes". I learned a great deal from him and had a lot of fun working with him. Prafulla deserves a great appreciation and high respect for his patient instructions and kind guidance through out my stay at SLAC from starting of my analysis towards the completion of this thesis and the paper. I am very thankful to Prafulla for being there whenever I was looking for help.Whilst serving as Data Quality Manager for the BABAR collaboration I had the opportunity to work with wide range of collaboration members. I would like thank to my wonderful colleagues at IR2 during this times, in particular to the OEP group members who were always around to help and were great pleasure to work with.I also have to thank my paper committee, Georges Vesures, Gerry Lynch, Brain All known interactions between matter particles can be explained in terms of only four fundamental forces, which in order of increasing strength are the gravitational force, the weak force, the electromagnetic force, and the strong force. The gravitational force acts between particles with mass and is responsible for the binding of matter on a cosmic and planetary scale, but because of its small strength it has negligible effect on high energy physics phenomena.The weak force acts upon particles with weak charge (all leptons and quarks) and is responsible for some of the spontaneous decays of particles (e.g., the radioactive 2 nucleus β decay). Since the weak force is short lived so all the massive particles created at the birth of the universe have since decayed to less massive particles that compose the world we live in today.Particles with electric charge (all quarks and the three charged leptons) interact through the electromagnetic force, the force which binds the atoms and molecules together. The theory which describe this force is called QED.Finally, the color force (also known as strong force) acts between the particles with color charge (all quarks but not the leptons) and is responsible for the confinement of the quarks inside a hadron (and of course on a larger scale, for binding the hadrons in a nucleus). The color force is known to work under the QCD (Quantum Chromodynamics). Both the electromagnetic and strong force conserve quark and lepton flavor.When the two matter particles interact through a fundamental force,...
