Measurement of the average time-integrated mixing probability of b-flavored hadrons produced at the Tevatron

We have measured the number of like-sign (LS) and opposite-sign (OS) lepton pairs arising from double semileptonic decays of $b$ and $\bar{b}$-hadrons, pair-produced at the Fermilab Tevatron collider. The data samples were collected with the Collider Detector at Fermilab (CDF) during the 1992-1995 collider run by triggering on the existence of $\mu \mu$ and $e \mu$ candidates in an event. The observed ratio of LS to OS dileptons leads to a measurement of the average time-integrated mixing probability of all produced $b$-flavored hadrons which decay weakly, $\bar{\chi} = 0.152 \pm 0.007$ (stat.) $\pm 0.011$ (syst.), that is significantly larger than the world average $\bar{\chi} = 0.118 \pm 0.005$.Comment: 47 pages, 10 figures, 15 tables Submitted to Phys.

Search for Kaluza-Klein Graviton Emission in ppˉp\bar{p} Collisions at s=1.8\sqrt{s}=1.8 TeV using the Missing Energy Signature

We report on a search for direct Kaluza-Klein graviton production in a data sample of 84 ${pb}^{-1}$ of \ppb collisions at $\sqrt{s}$ = 1.8 TeV, recorded by the Collider Detector at Fermilab. We investigate the final state of large missing transverse energy and one or two high energy jets. We compare the data with the predictions from a $3+1+n$-dimensional Kaluza-Klein scenario in which gravity becomes strong at the TeV scale. At 95% confidence level (C.L.) for $n$=2, 4, and 6 we exclude an effective Planck scale below 1.0, 0.77, and 0.71 TeV, respectively.Comment: Submitted to PRL, 7 pages 4 figures/Revision includes 5 figure

Combined Tevatron upper limit on gg->H->W+W- and constraints on the Higgs boson mass in fourth-generation fermion models

Report number: FERMILAB-PUB-10-125-EWe combine results from searches by the CDF and D0 collaborations for a standard model Higgs boson (H) in the process gg->H->W+W- in p=pbar collisions at the Fermilab Tevatron Collider at sqrt{s}=1.96 TeV. With 4.8 fb-1 of integrated luminosity analyzed at CDF and 5.4 fb-1 at D0, the 95% Confidence Level upper limit on \sigma(gg->H) x B(H->W+W-) is 1.75 pb at m_H=120 GeV, 0.38 pb at m_H=165 GeV, and 0.83 pb at m_H=200 GeV. Assuming the presence of a fourth sequential generation of fermions with large masses, we exclude at the 95% Confidence Level a standard-model-like Higgs boson with a mass between 131 and 204 GeV.We combine results from searches by the CDF and D0 collaborations for a standard model Higgs boson (H) in the process gg→H→W+W- in pp̅ collisions at the Fermilab Tevatron Collider at √s=1.96  TeV.

SOSIALISASI PEMBUATAN ABON HERBAL KEPADA MASYARAKAT KELURAHAN ANAWAI KOTA KENDARI

Berkembangnya wabah Corona Virus Disease-19 (Covid-19) di dunia, hingga ke sejumlah wilayah yang ada di Indonesia, tentu sangat menghawatirkan seluruh masyarakat, termasuk penyebarannya telah di temukan di Kecamatan Wua-Wua Kelurahan Anawai Kota Kendari. Tujuan dari kegiatan melakukan kegiatan sosialisasi pembuatan abon herbal kepada masyarakat Kelurahan Anawai Kota Kendari adalah meningkatkan kemandirian masyarakat dengan memanfaatkan potensi, keahlian, dan kemauan dari masyarakat, memberikan informasi tentang keberagaman produk pangan hasil ternak salah satunya abon herbal dan manfaat abon herbal bagi kesehatan tubuh, serta mendukung dan menguatkan ekonomi secara pribadi, kelompok masyarakat ataupun daerah sekitar Kelurahan Anawai Kota Kendari. Metode pelaksanaan sosialisasi yang digunakan dalam kegiatan Pengabdian Kepada Masyarakat (PKM) ini adalah kegiatan sosialisasi dan pendampingan kepada masyarakat. Dengan adanya kegiatan sosialisasi tentang pembuatan abon herbal kepada masyarakat di Kelurahan Anawai dan kegiatan pendampingan langsung ke masyarakat, diharapkan masyarakat lebih memahami tentang perlunya asupan protein hewani untuk kesehatan tubuh terutama pada saat masa pandemi seperti saat ini
