Fermilab’s new Recycler Ring will recover and cool “used” antiprotons at the end of a Tevatron store and also accumulate “new” antiprotons from the antiproton source. A wideband rf system based on barrier buckets will result in unbunched beam, grouped in one to three separate partitions throughout the ring. A new beam position monitor system will measure position of any one partition at a time,...

For many probability distributions of interest, it is quite difficult to obtain samples efficiently. Often, Markov chains are employed to obtain approximately random samples from these distributions. The primary drawback to traditional Markov chain methods is that the mixing time of the chain is usually unknown, which makes it impossible to determine how close the output samples are to having t...

E-waste or electronic waste is a major waste stream resulting from the boom in consumer electronics in the past decades. With the rapid pace of technology innovation and obsolescence that leads to shortened product lifespans, the growing demand for electronics and its resulting waste poses a significant challenge in every stage of its life-cycle from the utilization of raw materials, production...

We study the production of a charged Higgs boson in association with a W boson at the CERN Large Hadron Collider in the context of the minimal supersymmetric extension of the standard model. This production mechanism is particularly promising if the charged Higgs boson is too heavy to be generated by top-quark decay. We compare the contributions due to bb̄ annihilation at the tree level and gg f...
