New Techniques in the Search for Z' Bosons and Other Neutral Resonances

The search for neutral resonances at the energy frontier has a long and illustrious history, resulting in multiple discoveries. The canonical search scans the reconstructed invariant mass distribution of identified fermion pairs. Two recent analyses from the CDF experiment at the Fermilab Tevatron have applied novel methods to resonance searches. One analysis uses simulated templates to fit the inverse mass distribution of muon pairs, a quantity with approximately constant resolution for momenta measured with a tracking detector. The other analysis measures the angular distribution of electron pairs as a function of dielectron mass, gaining sensitivity over a probe of the mass spectrum alone. After reviewing several models that predict new neutral resonances, we discuss these CDF analyses and potential future applications

Take this Letter to my Mother

[Verse 1] Take this letter to my mother,Far across the deep blue sea,It will fill her hear with pleasure,She’ll be glad to hear from me.How she wept when last we parted,How her heart was filled with pain,When she said, “good-bye, God bless you,We may never meet again.” [Chorus] Take this letter to my mother,Far across the deep blue sea,It will fill her heart with pleasure,She’ll be glad to hear from me. [Verse 2] Take this letter to my mother,It will fill her heart with joy,Tell her that her prayers are answered,God protects her absent boy.Tell her to be glad and cheerful,Pray for me where’er I roam,And ere long I’ll turn my footstepsBack towards my dear old home, [Chorus] [Verse 3] Take this letter to my mother,It is filled with words of love.If on earth I’ll never meet her,Tell her that we’ll meet above.Where there is no hour of parting,All is peace, and love, and joy,God will bless my dear old mother,And protect her only boy. [Chorus

My Father\u27s Growing Old

[Verse 1]O! when I gaze upon his face,That once was young and fair,I almost weep to think that ageCould leave its image there,he stood the many storms of lifeThat round his pathway rolled,He\u27s resting in life\u27s sunshine nowMy Father\u27s growing old. [Chorus]I sit beside his easy chair,His and in mine I hold,He breathes his life yet sweetly there;My father\u27s growing old. [Verse 2]O! who can tell a father\u27s love,When age bringson decay,The form grows weak, the eyes are dim,The mind fades fast away,\u27Till after a while life\u27s sun goes downThe story then is told;Time whispers gently in my earMy father\u27s growing old. [Chorus] [Verse 3]His journey to the grave is short,His work is almost done,His tot\u27ring limbs grow weaker still,His race is nearly run;Old age deserts him on the road,He waits for death to come,he\u27s lost upon the Shores of Time,But Angels lead him home. [Chorus

I\u27ll Remember You, Love, In My Prayers

Making the selectable marker bar tighter and more economical

Use of the bacterial basta resistance gene (bar) as a selectable marker in Neurospora was reported by Avalos et al (1989 Curr. Genet. 16:369-372)
