A search for pair production of heavy scalar leptoquarks (LQs), each decaying into a top quark and a τ lepton, is presented. The search considers final states with an electron or a muon, one or two τ leptons that decayed to hadrons, and additional jets. The data were collected in 2016 in proton–proton collisions at √s = 13 TeV with the CMS de

Events with no charged particles produced between the two leading jets are studied in proton-proton collisions at √s = 7 TeV. The jets were required to have transverse momentum p jet T > 40 GeV and pseudorapidity 1.5 < |ηjet| < 4.7, and to have values of ηjet with opposite signs. The data used for this study were collected with the

The relative yields of ϒ mesons produced in pp and Pb-Pb collisions at ffiffiffiffiffiffiffi sNN p ¼ 5.02 TeV and reconstructed via the dimuon decay channel are measured using data collected by the CMS experiment. Double ratios are formed by comparing the yields of the excited states, ϒð2SÞ and ϒð3SÞ, to the ground state, ϒð1SÞ, in both

This Letter presents the observation of the rare Z boson decay Z → ψlþl−. Here, ψ represents contributions from direct J=ψ and ψð2SÞ → J=ψX, lþl− is a pair of electrons or muons, and the J=ψ meson is detected via its decay to μþμ−. The sample of proton-proton collision data, collected by the CMS experiment at the LHC at a cen

Sering kali kita diutarakan pertanyaan dari seorang perempuan yang ingin mencari pasangan hidup, antara keinginan keluarga dan pilihan hati, yang mana perlu diutamakan. Ada ketikanya keadaan menjadi tegang sehingga mengeruhkan hubungan seorang bapa dengan anak perempuannya. Ada kalanya juga ia menjadi punca tekanan yang kuat di dalam diri seorang a

Sejak kebelakangan ini, amalan Nikah Al-Khitbah menjadi perbualan umum terutamanya di kalangan mahasiswa di peringkat universiti. Terlalu banyak pertanyaan yang sering diutarakan sehingga menyebabkan rasa terpanggil untuk mengkaji dengan lebih mendalam masalah tersebut. Kajian ini cuba merungkai pengertian serta asal usul istilah Nikah Al-Khitbah,

Bio-pellet is an important fuel for sustainable energy in future and a potential renewable energy substitute for rural areas, East Java of Indonesia in particular. One of the candidates for solid fuel is coffee husk pellets, it is a bio-product produced from coffee production waste. In this research, focus is on hole design of stove that could be u

Ibadah adalah suatu kewajipan yang dituntut di dalam Syariah Islam. Ibadah perlu dilaksanakan disepanjang masa. Namun, di dalam keadaan tertentu, Allah s.w.t. memberi keringanan serta kelonggaran sebagai tanda rahmat dan kasih sayang Allah s.w.t. terhadap hamba-hambaNya. Penulisan ini cuba membincangkan perihal keadaan serta hukum berkaitan ibadah

Sejak kebelakangan ini, amalan Nikah Al-Khitbah menjadi perbualan umum terutamanya di kalangan pelajar universiti. Terpanggil dengan pertanyaan-pertanyaan yang sering diutarakan oleh para pelajar sendiri, penulis cuba merungkai beberapa permasaalahan berkaitan perkara tersebut menurut perspektif Islam. Pengertian Nikah Al-Khitbah, ciri-ciri, hukum,

A search for the electroweak production of supersymmetric particles in protonproton collisions at a center-of-mass energy of 13 TeV is presented in final states with a τ lepton pair. Both hadronic and leptonic decay modes are considered for the τ leptons. Scenarios involving the direct pair production of τ sleptons, or their indirect production
