1. Title <strong>of</strong> Project: W boson pair production in ep scattering<br />
Project Leader: Caesar Palisoc<br />
Source <strong>of</strong> Funding: OVCRD<br />
Grant Amount: PhP 197,410.00<br />
Duration: 1 September <strong>2006</strong> to 31 August <strong>2007</strong><br />
<strong>The</strong> production <strong>of</strong> W Boson pair in electron-proton scattering is to be investigated. Like the<br />
familiar electron and proton, the W boson is a realizable and detectable particle, but unstable<br />
with a short lifetime. A few <strong>of</strong> the W boson's physical properties, like its mass and lifetime for<br />
instance, are the subject <strong>of</strong> intense research since it's discovery in 1986, with their values<br />
experimentally determined with impressive precision. However, a few more <strong>of</strong> its physical<br />
properties, like how strong or feable it couples with other realizable particles, are not as<br />
constrained and are awaiting further precision test: an activity the proposed study will contribute<br />
on. <strong>The</strong> study is timely and has not been dealt with yet in the literature. Measurement <strong>of</strong> the<br />
cross section <strong>of</strong> the process in this study is underway in one laboratory and it would be<br />
interesting to see how results from this measurement compares with the theoretical predictions<br />
the study here aims to obtain.<br />

2. Title <strong>of</strong> Project: Charmonium and Jet Associated Production in positron-electron Collision<br />
Project Leader: Caesar Palisoc<br />
Source <strong>of</strong> Funding: OVPAA<br />
Grant Amount: PhP 15,000.00<br />
Duration: 1 July <strong>2006</strong> to 30 June <strong>2007</strong><br />
<strong>The</strong> associated production <strong>of</strong> charmonium and a hadron jet in positron-electron collision is to be<br />
studied to leading order within the factorization formalism <strong>of</strong> nonrelativistic quantum<br />
chromodynamics. <strong>The</strong> charmonium plus hadron jet associated production in positron-electron<br />
collision involves subprocesses where one (both) <strong>of</strong> the initial state photons is (are) highly<br />
virtual. To the best <strong>of</strong> my knowledge, this process has not been dealt with yet in the literature<br />
and since this process proceed via color-octet (CO) subprocesses, conclusions therefrom will<br />
help<br />
determine if CO processes are realities <strong>of</strong> nature or not.<br />
