Ahmad then travelled to United Kingdom and attended Imperial College London where he began his doctoral studies under Abdus Salam's physics group.
In 1970, along with Fayyazuddin, he carried out the work on construction of Veneziano representation for pion photoproduction amplitude, in which he predicted that, keeping the π and the ρ trajectories, the zero-free parameter fits for the sum and the difference of the differential cross sections for unpolarised photons and the asymmetry function Σ(π++π−) are obtained.
[6] Prior to the discovery of Alfvén wave in hydromagnetics in 1969, Ahmad was engaged as a theoretical physicist, working in the fields of quantum, molecular, and nuclear physics.
In 1970, on an advice of Abdus Salam, Ahmad went to Italy to join International Centre for Theoretical Physics (ICTP) to pursue his further doctoral studies.
[8] In January 1972, Abdus Salam called one of his eminent students from Italy to report to Pakistan Atomic Energy Commission's chairman Munir Ahmad Khan.
The Theoretical Physics Group directly reported to Abdus Salam who coordinated the research on metallurgy, weapon chemical lenses, enrichment, separation and reprocessing of the fuel.
Under the leadership of PAEC chairman Munir Ahmad Khan, the TPG's theoretical designed bomb was successfully cold tested, codename Kirana-I, in 1983 near at the Kirana Hills.
In an honorary conference along with PAEC chairman Parvez Butt and IAEA's delegation, Masud Ahmad said: "There is an urgent need to disseminate related information on radioisotope based analytical techniques to end user institutions engaged in mitigation of marine pollution.
The unplanned disposal of untreated industrial, domestic and agricultural wastes into seawater has led to contamination of the coastal areas of many developing countries in South Asia resulting into considerable increase in the concentration of toxic elements".
[16] He also included that "these toxic elements have posed a threat to the marine life occasionally witnessed in the form of mass mortality of fish.
