A search for charmed baryons decaying to D{sup 0}p reveals two states: the {Lambda}{sub c}(2880){sup +} baryon and a previously unobserved state at a mass of [2939.8 {+-} 1.3 (stat.) {+-} 1.0 (syst.)] MeV/c{sup 2} and with an intrinsic width of [17.5 {+-} 5.2 (stat.) {+-} 5.9 (syst.)] MeV. Consistent and significant signals are observed for the K{sup -}{pi}{sup +} and K{sup -}{pi}{sup +}{pi}{sup -}{pi}{sup +} decay modes of the D{sup 0} in 287 fb{sup -1} annihilation data recorded by the BABAR detector at a center-of-mass energy of 10.58 GeV. There is no evidence in the D{sup +}p spectrum of doubly-charged partners. The mass and intrinsic width of the {Lambda}{sub c}(2880){sup +} baryon and relative yield of the two baryons are also measured.

The SELEX experiment (E781) at Fermilab has observed two statistically compelling high mass states near 3.6 GeV/c2, decaying to?{sub c} K−?+ and?{sub c}+ K−?+?+. These final states are Cabibbo-allowed decay modes of doubly charmed baryons?{sub cc}+ and?{sub cc}{sup ++}, respectively. The masses are in the range expected from theoretical considerations, but the spectroscopy is surprising. SELEX also has weaker preliminary evidence for a state near 3.8 GeV/c2, a high mass state decaying to?{sub c}+ K−?+?+, possibly an excited?{sub cc}{sup ++} (ccu*). Data are presented and discussed.

This book is a new look at one of the hottest topics in contemporary science, Dark Matter. It is the pioneering text dedicated to sterile neutrinos as candidate particles for Dark Matter, challenging some of the standard assumptions which may be true for some Dark Matter candidates but not for all. So, this can be seen either as an introduction to a specialized topic or an out-of-the-box introduction to the field of Dark Matter in general. No matter if you are a theoretical particle physicist, an observational astronomer, or a ground based experimentalist, no matter if you are a grad student or an active researcher, you can benefit from this text, for a simple reason: a non-standard candidate for Dark Matter can teach you a lot about what we truly know about our standard picture of how the Universe works.
